No, that's when life is currently believed to have begun.About 3.5 billion years. Probably somewhat longer.
Single-celled life. Multicellularity wasn't observed until the PreCambrian, 550-600 mya as the timeline is currently understood.
Beneficial mutations being exceedingly rare, they cannot account for the Billions of species and their diversity that have ever lived within the 600 my.
Stasis for 3 b-y, then an explosion of life appearing abruptly and growing since?
There's no way naturalism, i.e., evolution, reasonably explains it. It just isn't observed
