What is your hypothesis to explain the origin of human?

Everyone has a different hypothesis. Scientists believe that Earth was formed by lava and gravity and such ... Believers in god believe that it was formed by god himself who created adam and then eve from adam's rib and dirt. I believe people's origin actually comes from a living organism or bacteria of some sort. Such as fish. It is proved that people come from fish. But if you think about it, think about your mom, then her mom, then her moms mom and continue that chain. We are all related if that makes since.
