Exactly, that's one of the cornerstones of the conspiracy theory - the cover up. The lack of evidence just proves "they" covered it up. Any facts "we" have that disprove the conspiracy are just the facts that "they" feed us.
Trump is one of the Lizard People and Chelsea Clinton is actually his and Hillary's offspring. The Lizard People are shape shifters and have been walking among us for centuries. The Lizard People have been covering up their existence since they first arrived on earth.
Personally, I prefer a higher standard of proof than the lack of proof is the proof. I prefer a higher standard of proof than a standard that allows one make up anything they want and claim its a fact (ie Trump is a shape shifting Lizard Person). If you're standard is it's all a cover-up, etc, then you believe in conspiracy theories and that's why people call your narratives conspiracy theories. Minus facts these narratives are actually works of fiction.
In the case of "The Great Steal," we're talking a cover up of millions of people - seems highly unlikely the Lizard People could cover that up, but then again they have been walking among us for centuries, so if anybody is capable of pulling off the big steal, it's them.
