The incredibly narrow and selective god argument (for lack of a better name) I am sure someone already has come up with a way better name for it. Feel free to tell me about it :)

--------------The "Too long did not read" version of the narrow god argument------------------

If the universe in time and size was reduced to a beach that was 75 years old:

God did everything he did in the bible to 5% of the surface of a single grain of sand on that beach. And god did nothing for 75 years before doing anything on that grain of sand, at least that is worth mentioning more than just passing in the bibles/holy books, (other than start the process to create it,) until the most recent 8 minutes of the beaches 75 year old life. 3 minutes to fit in all his action, and 3-5 minutes to sit back and watch. (Depending on your major religion's holy book.)

Furthermore, all he did only applies to 3% of the human population that lives or have lived on that grain of sand. The other 97% only pissed god off for getting it completely wrong and according to many religious interpretations are doomed to suffer forever for it, instead of paradise forever.

These extremely narrow and small numbers are actually incredibly generous on my part. It is almost certainly far, FAR narrower then that. (Especially on the grain of sand vs beach thing.) I could argue its a single grain of sand on all of earth, 1 minute of the beaches 75 years so far, and only 0.1 percent of the earth's all time human lives.

-----------------------------The details if you want them------------------------------------

Current scientific evidence/knowledge/consensus puts the universe at 13.4 billion years old. So, if we took the various major religion's holy book's as proof of gods interaction, nearly all the major religions had major "god interaction" for an incredibly narrow slice of time. 90+ percent of the holy books only talk about all this god interaction stuff for a couple hundred year time span.

Lets give these holy books even more benefit of the doubt. We will say 1000 years (VERY GENEROUS really) but this just highlights the scale. Big numbers are hard to understand for anyone really, yes, us atheist too. So we have to put this on a scale we can begin to understand.

13.772 billion years divided by 1000 years = 13.772 million. taking an average human lifetime to scale to numbers we can sort of understand, 75*365*24*60 = 39,420,000 minutes. divide 39.420 by 13.772 = 2.86 minutes for a human in his entire life time is 1000 years the universe has been around. We will round up to 3 minutes, being even more generous. (Plenty of generosity to give on this point because it is so powerful/extreme.)

So in human terms, you live to a ripe old age of 75 years. All that time you do nothing but created the heavens, allowed life to grow on this particular planet etc etc. Got alot done. But all of that was just setting the stage for humans, "gods children" Now you are 75, not a big deal you will probably live into your 100's (The universe is theorized to live this long based on current estimates.) maybe more, maybe less give or take a dozen years. But in this tiny 3 minute span you suddenly get VERY busy. Everything in the bible is well covered in this tiny 3 minute span compared to 75 years of just sitting back. You then take a 3-4 minute breather,again doing nothing too out of the ordinary, and we are where we are now, in the present.

(Btw if you think the universe is only ~6000 years old, I do not want to argue with you, you are ignoramus personified.) This argument also shows why some religious people insist that all of creation is only 6000 years old, because 13.4 billion years is a crazy amount of idle time.

Remember how generous I was with the numbers that is an extremely narrow slice of time.

-----------------------------------------------
The next part of the narrowness argument. The universe is big, so impossibly big it impossible to imagine. Let's say the universe is a big as the earth to bring it down to semi imaginable dimensions. Here again is where I will be extremely generous for theist. We will make earth the size of a single small grain of sand (in reality it would be far far smaller than a grain of sand.)

Ya know what, all the grains of sand/earth on the planet is still impossible to imagine. I will concede another couple thousand factors of scale. Because again this argument can still be easily made even having the real scale be so far off from the actual scale. Just imagine a beach with all its grains of sand. God creates that entire beach, but he only cares about a single grain of sand on that beach. And on that grain of sand he does everything in that incredibly narrow slice of time, on only less than 5% of the surface of that particular grain of sand. All of the various major religion bible history takes place on 1 grain of sand, during 3 minutes of his 75 minute life span.

Narrowness number 3. Christianity is the largest religion by. We will ignore the fact that within christianity it is very divided on many major details. But lets say this god is fine with that, as long as they got the major Christianity detail right. That still only comprises maybe 3 percent of all the people that ever lived or currently alive. Remember huge chunks of that number were people that said they were christian but rarely practiced religion or thought of god, but god is fine with that too, just say your are Christian on human created polls, does not matter if you are good or bad and all of god's creation was worth it.

So we got Christianity's god, today's by far largest religion in a time that has by far the largest population of humans on earth.
God Created an entire incredibly complex beach, but only cares about 5 percent of the surface of 1 grain of sand. He waited 75 years to do everything in 3 minutes, and he only cares about the 3 percent of the human population on that beach, the rest can literally get tormented for all of eternity while that 3 percent gets to go to paradise.
