Evolution of life 

Three and a half billion years ago, there was nothing on planet earth but nucleic acid, lying in the sea. About 1.6 billion years later, bacteria formed in the sea, along with archaea and eukaryotes. At that point, life began in the sea.  About 7 million years later, living things in the sea formed, creating new species such as octopuses, snails and worms. About 600 million years later, animals from the sea, began moving to land thus creating life on land.

The first fish to walk on land was called Tiktaalik, but unfortunately, the Tiktaalik species went extinct long ago. Overtime, fish from the sea would evolve to new, different species. Two hundred and thirty million years later, Tetrapods, amphibians, Marsupials, Reptiles, Birds, and Eutherians became new species. Over time, those species evolved into a lot of different species such as Tuatara, Kangaroos, Elephants and much more.

Eight million years ago, Eutherians later evolved into primates. Primates learned to fight, hunt and a lot of other things we learn now (besides modern-day things), therefore, making primates smarter overtime. 

After two million years, primates evolved into humans. Overtime, humans gained more intelligence and started creating modern technology we use now.
