Ok Lmale and any others,
Let's get into the depths of theory:

First were the word came from:

From Yahoo Answers:
Where did the word 'theory' come from?
What archaic word(s) did it originate from?
Greek - theoria: "contemplation, speculation, a looking at, things looked at"

Greek - theorein: "to consider, speculate, look at"

Greek - theoros: "spectator"

Above is the original and true meaning of the word theory in 1590s. Then someone had to change it in 1630 to accommodate the unprovable so called science beliefs to try and take God out of the equation. The Bible even tells us to beware of false science.

1 Timothy 6:20 KJV
O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:

You see God believes in real science, and put it in His word. Another word for science falsely so called is - evolution.

Below is today's version of the word theory from Wikipedia:

You will notice in the second section, it says "confirmed through observation and experimentation".
I have yet to see an experiment that proves " something from nothing" nor of a big bang, nor of life from non life.
By the way none of those have been observed either.

In the third section, "As additional scientific evidence is gathered, a scientific theory may be rejected or modified if it does not fit the new empirical findings"
In other words if someone finds a hole in the evolutionists theory they can just think up something new and put that forth as a so called evidence, which is not really evidence, it's just a thought with nothing to observe nor experiment with.

Making it for you faith!!!!!!!!!
I rest my case, unless you need me to go on.

Wikipedia:
Theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works.

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.[1][2] As with most (if not all) forms of scientific knowledge, scientific theories are inductive in nature and aim for predictive power and explanatory force.[3][4]

The strength of a scientific theory is related to the diversity of phenomena it can explain, and to its elegance and simplicity (Occam's razor).[citation needed] As additional scientific evidence is gathered, a scientific theory may be rejected or modified if it does not fit the new empirical findings- in such circumstances, a more accurate theory is then desired. In certain cases, the less-accurate unmodified scientific theory can still be treated as a theory if it is useful (due to its sheer simplicity) as an approximation under specific conditions (e.g. Newton's laws of motion as an approximation to special relativity at velocities which are small relative to the speed of light).[citation needed]

Scientific theories are testable and make falsifiable predictions.[citation needed] They describe the causal elements responsible for a particular natural phenomenon, and are used to explain and predict aspects of the physical universe or specific areas of inquiry (e.g. electricity, chemistry, astronomy). Scientists use theories as a foundation to gain further scientific knowledge, as well as to accomplish goals such as inventing technology or curing disease. Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge.[3] This is significantly different from the common usage of the word "theory", which implies that something is a conjecture, hypothesis, or guess (i.e., unsubstantiated and speculative).
