How long the earth has been around and how many species have died out is all unknown, but this "one species turned into an entirely different species" bullshit that evolution posits has yet to be proven, and it never will be. It doesn't happen now (at least not without unnatural practices in a lab), and it never happened before. Anyone who thinks all the various complex and/or simple biosystems on earth could just happen by chance is the individual in need of "medication".
Whereas he who thinks something complex enough to design all this complexity exists neither by chance or design, but still somehow exists, is perfectly fucking sane
