Darth Maul is Snoke because we never saw him die
Leia is Snoke becase she is force sensitive
Boba Fett is Snoke because muh attachment to a 1 dimensional character who fell into a pit and dies

and i'm not saying Kinder is Snoke, but has anyone seen Kinder and Supreme leader Snoke in the same room together? Think about it

Hayden Christensen is Snoke

Better yet. Snoke is that old man that Hayden replaced as Anikin at the end of Return of The Jedi who's now out for revenge, and that's how he convinced Ben that his grandfather wanted him to turn to the dark side.

Jar Jar is Snoke. The whole "Meesa goan die" talk was a clever rouge. Who led the Jedi to Anikin? Jar Jar.  After manipulating the Senate, who was the deciding vote giving the puppet Palpatine imperial powers? Jar Jar.

Jar Jar = Snoke

Snoke is love, Snoke is life.

Sebulba is Snoke

He wants revenge on the Skywalker lineage after the pod race loss.
