Who is to say when the sun captured the earth?

If the Earth did not form in its place, something else would have, in order to satisfy Bode's Law. Unless you can propose a mechanism by which the original Earth was replaced by this one, we'll just have to assume that it formed in its current orbit.

I would think that would fascinating to study if I were a scientist,

Indeed. A magic wand would likewise employ many graduate students; it would behoove me to start believing in them.

Why is there no search for evidence of these things when they already suspect the big crunch that goes hand in hand with the biblical depiction?

Unfortunately, observations published early this year rule out any "big crunch" in our future. It rather looks as if the universe will expand away to infinity.

They may have written off the big crunch a little too early, wouldn't be the first time science had to revise. God says he is the Alpha and the Omega. If aplha is x, the big bang, and omega is y, the big crunch, the universe would expand to a certain point then be pulled toward the omega, and in it's collapse the stars would blur and appear to fall. In fact, what if the unexpected speeding up of the universe is a result of being pulled toward the omega? I would like to know if this increase in speed is expotential, if it is, uh oh.

Science already claims that at one point the earth was watered from a mist that rose from the ground, I would think that would be a good place to start an investigation as to how that might coincide time wise with this explosion of species.
