Man has been trying to get along without God ever since Adam and Eve rejected His command in Genesis 3. The greatest push to ditch God since the Tower of Babel, though, is probably
the "theory" of evolution. Though scientists or other proponents of the "ToE," as it's called, will say that the "Big Bang" is separate from evolution, the whole kettle of (rotten) fish is inextricably tied together.
For one, the universe has to be here for evolution to take place, even though the only place anything has ever evolved is in the minds of willingly ignorant scientists. Therefore, first of all, we must understand the fantastical origins these people propose. In essence, billions of years ago (they don't know for sure when) something (they don't know what) exploded (they don't know how). Then, somehow, this unexplainable explosion created the galaxies, solar systems, stars, planets, moons, asteroids, Martians and Earth.
The next big pile of dog doo-doo is better known as "abiogenesis," or the rise of living things from non-living things. Make sense? Didn't think so. Basically, they teach (whilst sucking on a bong, apparently) that after the Big Bang (see above), the earth was a blob of hot, molten rock that gradually cooled down and developed a hard rocky crust. Somehow the earth developed an atmosphere of primitive oxygen and hydrogen and it began to rain on the rocky crust. The rain created a sludge after a few million years, and a "simple," single-celled organism arose from the muck. Somehow this little critter found something to eat (he's the only organic material in the universe!) and someone to marry (huh??) and began the great process of Natural Selection.
Now Evolutionists take something like dogs, for instance, and say that since all these dogs came from a common ancestor (feasible, no problem there), then we all somehow came from that little sludge in the last section. Now, how they come to this conclusion I'll never understand; it's way easier when you just let God do it.
In the beginning God created the heaven and the earth. Why use something stupid like evolution when you're God?
