Can't humans and animals coexist?

A common debate in the Sonic fandom is wether or not Sonic should live in a world inhabited by humans (like in Sonic Adventure) or inhabited by other anthropomorphic animals like him (like in Sonic Forces). My opinion is: Why not both? Is it really that hard to establish that anthropomorphic animals just evolved next to humans? If we were to erase all humans expect Eggman from this world, a big chunk of Sonic's lore (like G.U.N.) would be lost. Also, if they went back to the was of the Adventure games and had Sonic and his friends be the only anthropomorphic animals seen, that would raise too many questions. Just have them exist in the same world and problem solved.
