To the extent there is a consensus here, it's not an evidence-based one; it's entirely founded on untested statements made by people who have both a track record of lying and incentive to do so.
Demanding evidence from one party while accepting the word of the other is not even-handed.
And how is the corollary from the argument you just presented that neither side needs to provide evidence? Let's start by actually having evidence for "your side", then you can demand evidence from the other.
