Primative species lived. There's genetic proof of evolution. It would be stupid to think that we came from two lone people that were exactly like us.

There is no genetic proof of evolution. 0 none zip zero. Even the evolutionists agree they have 0 evidence. It is entirely speculation, and they have proven much of the so called evidence to be fakes. Every "caveman" species has been 100% proven to be faked. The museums and textbooks never point this out though.

Actually the Bible says the opposite is happening, we are getting worse, not better, we have drastically shorter lifespans etc... Adam and Eve lived over 900 years. The account of their geneology only tells about some of them. It doesn't say that Cain and Able were the only children. It specifically says they had sons and daughters. How many kids can you have in 900 years
