Evolution/creation 2

[Undeceived]

Research "ancient megafauna":

In prehistoric times--or "pre-Flood' as creationists say--organisms were generally larger. This was a result of a denser, milder atmosphere. Evolutionist scientists can't really explain how the earth arrived at this high-pressure atmosphere, but creationists theorize a water vapor canopy (referenced in Genesis 1:7). Higher pressure allows for thicker body structures and longer life. Judging by the ages in giant tortoises today, large dinosaurs may have lived hundreds of years. The same goes for humans.
Cain married his sister, just as Abraham married his half-sister. At that point complications associated with incest had not yet accumulated. There were also less diseases, allowing for longer lives.

Why do those same organisms continue to live fantastically long lives today in the absence of this vapor canopy that never existed to begin with?

The few that did were fit enough to survive--I sound like a natural selectionist. Most didn't. Two-foot cockroaches, giant crickets, grasshoppers, spiders and fleas. Dragonflies with a three foot wingspan. The evidence is undeniable. Google "megafauna" and see. There is a clear correlation between size and age today, so why shouldn't there have been then?

I am not looking to prove this, for even Evolutionists cannot prove their theories on this matter. I gave a Biblical/scientific explanation for why humans could have lived longer in pre-Flood times. I am not going to shift goalposts for you, Rhythm.
