Why did it take such a long time for humans to be formed?

Earth is 4.5 billion years old. Humans only 200,000 years. They were very late. How come?

  • Because of the definition of "humans."

    All organisms on Earth are descended from a common ancestor or ancestral gene pool. Current species are a stage in the process of evolution, with their diversity the product of a long series of speciation and extinction events.

    Humans have maybe 47,000 genes. If each one took 80,000 or 100,000 years to happen, then you can easily add that up to get over 3.7 billion years.

    Why does water that falls in the Rockies have to flow so damn far to make it to the ocean?

    Humans are not the objective, humans are a stop on the road. We just happen to be here, now. The road did not have to pass by here, and there is no reason except random chance that the road passes through humans. No guarantee that we will last for long either.

    There is no over-arching "why". there is just random process. No reason (as in purpose), really, that we even exist at all, never mind now, after all that time.

    It is evidently because of our brain development.

    Our brains are larger than similar sized animals.

    That brain was presumably used by our ancestors to find food and shelter and defend against wild animals.

    We now use that brain to go to the moon etc etc. Things that other animals can not even contemplate

    Humans are very intricate.
