In pre-SGW it was an alien invasion... an unintended invasion. One of the Xorda visited Earth but was shot down and dissected. The visitors race was furious by this that it bombed Earth with nuclear like "gene bombs" which ended all life on Earth but began the most earliest history of Mobius. Over time there was Mobosaurs, then the day Chaos Emeralds rained down, human decendants being partially dwarfish and three-fingered and so on.

Of course all that is removed from canon after the Super Genesis Wave.

Personally I believe that Sonic's Earth is the very same as our planet Earth, howeve rour world never had Gaia to begin with to cause all those Times of Awakenings that cause geological phenomenons thats form zones, or the evolution of Mobian.

In fact, I sometimes wonder if mobians and chao share the same ancestry, given chao are able to assimilate little creatures and gain traits and features similar to them.
