It's hardly because of fear. The thing is, it's like someone telling you 2+2=6.
Yeah, it may be close to the real answer, but it's still not the right one.
However, most of us do, in fact, try to learn as much as possible about it, but most of the explanations for evolution are unimpressive.
My belief, is that God use a variation of "evolution" that lets us adapt to the environment around us.
But the hypothesis that Humans (going way down the evolutionary chain) came from a grouping of cells, over the course just a few million years, is preposterous. Not only would evolution take far
longer than what even they say it would, but the odds of successful evolution all the way to where mankind is now, is so extremely low... It's literally unbelievable.
Let's take this for example, In order for even the most basic double-helix (of DNA) to form there needs to be all of the different chemicals gathered together in the same pool of liquid. Then for them to form into cells, they need to form into a very basic version of what we know as DNA, this alone is likely to take a few million years (without being disturbed in any way), but wait, we still need the RNA polymerase, Helicase and all the other enzymes needed for a cell to live AND reproduce, and if even the slightest thing goes wrong, gets misplaced or simply isn't there, the entire cycle gets shutdown.
Also, theoretically speaking, this cycle and the events leading to the creation of the new cell should still today be found in nature today, but has yet to actually be found.
I could go on writing all night about the invalidity of evolution, but I have school tonight and, therefor, need to study.
