What creatures inhabited the earth before God created man?

Answer 1

The earliest creatures on earth were micro-organisms that existed over one billion years ago. For many millions of years, the only life forms were fish and other marine creatures. Eventually, some fish evolved to be capable of spending time out of water, much as lungfish do today, and these evolved into the earliest amphibians.

Then came the age of dinosaurs, both the Jurassic period (205-141 million years ago) and the Cretaceous period which followed. We tend to think of dinosaurs as giant, lumbering creatures, but fossils have been found of dinosaur species smaller than a chicken, and the is no reason to believe that these were the very smallest dinosaurs ever. This was also a time when reptiles such as crocodiles evolved, as well as insects, Spiders and many other creatures.

After the extinction of the last dinosaurs, mammals were able to flourish. Many thousands of species have existed. One of the last creatures to inhabit the earth was man.
