Again, you show your utter stupidity. He is not asking you for evidence of the existence of something that does not exist.
His evidence of election fraud exists and has been shown to you.
He is asking that you provide evidence that his evidence of election fraud is fake.
I could show you a human in a Bigfoot costume and claim that is evidence of the existence of Bigfoot, then challenge you to prove that my evidence is fake. All you would have to do to prove my evidence is fake would be to take off the costume, thus proving the fact that my evidence is fake.
Now apply that to Lindell's challenge. Prove that his evidence is fake.
By the way, Lindell did not come up with all that evidence on his own. Watch the 2-hour video and see the parade of cyber tech experts and what they presented.
