Ok guys I was thinking about Atheism and stuff when my mind suddenly realized something strange:
I read a fact that said that the world is actually getting slower every rotation (Which is a true fact) and that in about a couple million years or so, Earth's average day would be 25 hours. So I then thought: Well what about a couple million years or so back??? The world would of had 23 hours in a day! And then I realized that about a billion years before, Earth must of been spinning so fast that life itself couldn't have been able to survive! And what are the chances of that NOT happening? So then does that mean that there is a God? D: PLEASE HELP!!! And also speaking of chances check this out: https://www.youtube.com/watch?v=qXXZLoq2zFc

Things you need to show:
1) Look up what the change in rotation rate is now for 1 year.
2) Assuming the result from #1 is approximately constant, work out the rotation rate at time -t in the past.
3) Show that the resulting acceleration from #2 is too high for life to survive.
I'm extremely suspicious about #3. When I was a child I did an experiment where I grew bean plants in a pie pan that was mounted to a record player revolving at 78 rpm and they grew just fine. And that is several hundreds of times more acceleration...
Well the spinning of Earth's rotation affects the weather and life: the spinning of the plant on the record player had daylight for an average 24 hour day but if the Earth was spinning that fast, then it would be constantly changing from night to day. You can look up the rotation of the Earth and see that it is getting slower. Most sites say because of the moon, however, can you tell how fast the world was spinning BEFORE there was the moon? Did life come from the moon?

No, it never spun so fast that it was uninhabitable, and the main reason we are slowing is because of a transfer of rotational momentum to the moon(which you should know if you studied tidal acceleration in school) which results in a leap second being added to our planetary time every 18 months or so.
So what was it like before the moon came? And what put the Earth in (almost) perfect condition for life? How did the rotation of Earth come upon 24 hours? I'm very curious please forgive me XD.
"How did the rotation of Earth come upon 24 hours?"
That is by definition...
"What put the Earth in (almost) perfect condition for life?"
Who told you the Earth is perfectly placed? The habitable zone is about 150 million km wide...
These questions/statements are generally known as Texas sharp shooting. You shoot at some random place on the wall, the go and draw a target on the wall, centered on your bullet-hole, then claim you are a sharpshooter.
I never said that Earth was perfect. lol And what do you mean by definition? Since I'm the Texas sharp shooter, then are you the person who never answers questions directly thus creating an illusion that you have answered? Don't answer these questions too seriously...
What don't you understand about definition?
How many Lunar days does it take for the Moon to rotate once? 1, because that is how it is defined.
How many Martian days does it take for Mars to rotate once? 1, because that is how it is defined.
How many Earth days does it takes for the Earth to rotate once? 1 because that is how it is defined.
See a pattern yet?
"So what was it like before the moon came?"
This is what gets so tiring about arguing with some people. If you actually take time to respond to them with some facts and information, next thing you know, they want you to explain encyclopedias worth of information to them. You know what? My education wasn't free, it took over a decade to pay off my student loans, so don't expect free classes in physics and geology as if the information didn't cost us anything at all.
"And what put the Earth in (almost) perfect condition for life?"
That's easy, the Earth isn't in anything approaching a perfect condition for life, and it formed via accretion.
"How did the rotation of Earth come upon 24 hours?"
The same way the speed of an object can slow to 5mph. Over the years it has slowed until it now takes close to 24 hours for a complete rotation, this isn't any more strange or incomprehensible as anything else slowing down.
"I'm very curious please forgive me XD."
No.
"The same way the speed of an object can slow to 5mph. Over the years it has slowed until it now takes close to 24 hours for a complete rotation, this isn't any more strange or incomprehensible as anything else slowing down."
So a couple million years before, was it spinning too fast for life to exist?

I never asked about your education or student loans. I asked you "So what was it like before the moon came?"
"No."
XD Why not? Does the world rotate around you?

If you actually bothered to READ, both the link I posted and my actual answer would have discomfited you from this notion. However, because you didn't, I now have to repeat that the Earth has never spun so fast that life could live on it. This should be apparent for two reasons:
1. The link provided should have shown you that billions of years ago, a "day" or full rotation was between 18 and 20 hours. If we take the circumference of our poor miserable planet(at the equator not its axis) and then divide that by the number of hours it takes for a rotation, we will see the speed:
Circumference: 24,901.55 miles (40,075.16 kilometers)
Today: 24,901.55 miles (40,075.16 kilometers)/24= 1037.56458333mph(1669.798336794636kmph)
Billions of years in the past: 24,901.55 miles (40,075.16 kilometers)/18= 1383.41944444mph(2226.397782392847kmph)
We are moving at over a thousand miles an hour at this moment. This, even if the effect of INERTIA didn't exist, would not be enough of a change in relative speed to kill anything.
2. The reason we aren't all dead despite the planet moving at speeds exceeding the speed of sound(768 mph), is because of inertia. Theoretically, the planet could move at speeds triple and quadruple what it does now, with little change other than the weather.
"I never asked about your education or student loans. I asked you "So what was it like before the moon came?""
Yes, you asked for a free education from people who had to pay for theirs.
"XD Why not?"
Because a cursory google search would have fixed your misconceptions, assuming you had cared enough to bother googling it.
"Does the world rotate around you?"
No, I don't live near the axis, perhaps I should move there so it will. I seriously doubt, however, that it would actually make people stop asking questions they could easily get the answers to on their own.
Travis - "Circumference: 24,901.55 miles (40,075.16 kilometers)
Today: 24,901.55 miles (40,075.16 kilometers)/24= 1037.56458333mph(1669.798336794636kmph)
Billions of years in the past: 24,901.55 miles (40,075.16 kilometers)/18= 1383.41944444mph(2226.397782392847kmph)"
yeah that works out to about 0.03 m/s^2 (today) and 0.06 m/s^2 in the distant past. Both of those are trivial (and explains why we don't notice them in our daily lives).
"So a couple million years before, was it spinning too fast for life to exist? "
So you are back to this non-sense again. Do you do the calculations I suggest? Care to share them with the class?
This sounds like it's just some "trolling" to me. To irritate and see if an atheist with weak knowledge and conviction will take the bait.
This is an intriguing thread. I'm little confused with the questions of the thread starter. I can't feel the earth rotated faster today than of yesterday.
It is a young earth creationist argument with the following form:
Step 1) measure the rate of change of something today
Step 2) apply this rate of change going backwards in time
Step 3) conclude that the results of step 2 will make life impossible, therefore life/earth can't be that old
Example:
1) In the last 100 years average temperature has gone up by about 1C.
2) Therefore 30,000 years ago the average temperature must have been absolute 0.
3) Life isn't possible at that temperature therefore life can't be 30,000 years old.
Of course the flaw with this line of thought is that rate of change, changes. The rate of change in the past is almost never what the rate of change is now.
The funny thing is about the example in the opening post is that even if you do make this assumption, it does not make life impossible in the past.
Unpossible. There are points on the planet that defy the 24 hour rule, always have, and have supported life from the "soup" to now. Get your head around it and stop with the pseudo-science/overactive imagination nonscience (aka nonsense). And put your big guy pants on while you're at it.
