Lol, i understand where you're coming from.
Let's first be more clear about this sort of stuff. XP
Natural Selection (in the form of Microevolution) is INDEED TRUE
however, when it comes down to Macroevolution (Darwinism and Evolution) it's NOT true. There is NO scientific evidence for ANY sort of "change in kind". There has only been evidence for a change in species.
(meaning...there is NO evidence whatsoever for a change--Dog to cat. Instead, Darwin only saw the change in species, etc--in the beak of the finches. The finches REMAINED FINCHES. they didn't turn into lizards, etc.)
So technically...Darwin made up all that based on a species that was adapting to circumstances. Adaptation and Evolution are TWO VERY DIFFERENT THINGS.
Then, the Big Bang...
The Bible has NO evidence whatsoever for the Big Bang. Instead, it provides the fact that God created the world in 7 days.
Think about it. The Big Bang would have had to come from Nothing. Why would GOD create a Big Bang? If God exists (and we KNOW He does), why would HE write down in the Bible the way he created the world, and NOT FOLLOW THAT?
There is NO evidence in the Bible for a Big Bang. So....what has you confused? ^__^
