    The first animals came about 3 hours and a half after the multiellular cells came around.Unfortunately the animals were very simple.

    The First Complex Animals About 8:42 PM

    The first complex animals appear 16 minutes before the first fish in the water.

    First Fish And Proto-Amphibians About 8:58

    The First animals in the water appear 27 Minutes after the first animals. Mind that the fish and proto-amphibians are complex animals.

    The First Land Plants Around 9:06 PM

    The first land plants appear 13 Minutes before the first insects and bugs. How did they reproduce without seeds? The world may never know. But we wouldn’t here without them. All the plants give energy to the food we eat and they give us oxygen.

    The Present Day

  • The First Life About 5:00 AM

    The earliest forms of life appeared approximately 4 hours and 52 minutes after the Earth was created. These forms of life were very simple; complex cells had not appeared yet and thus prokaryotes, or simple cells, were the only cells around.

  • First Complex Cells Around 1 PM

    Unfortunately, it took a long time for complex cells to be created. 13 hours after the earth was created, complex cells starting evolving.
