I'm not sure of the timing, but at some point ocean-based plants began working their way onto land. Also, the best available fossil evidence points to a certain type of lungfish as the first animal to venture onto land, although giant scorpions could also do this.

How did life get started is a question where there is no scientific answer. There are many religious answers and you believe what you religion says.
