Some might call that faith.
Not me, I'd call it trust.
1. We have enough scientific understanding of the universe and its immensity to expect that many forms of intelligent life have evolved in it at one time or another.
2. I see no evidence that evolution led to the creation of sentient beings that somehow required external agency to become sentient and conscious, There is no evidence that some external plane of reality somehow intersects with our physical brains to generate our minds or consciousness in any way and to postulate one begs more questions than it answers. So Occam's Razor kicks in too. It's safer to assume that our brains are totally ontologically responsible for our consciousness even if the brains cannot be used as a epistemological basis to describe experience.
3. Human already possess suffiicient ability to generate virtual worlds and I see no reason why this ability should not increase, perhaps exponentially, for some time to come.
4. That leaves AI. No, we haven't figured out how to create sentient or conscious AI beings yet. But I think the burden of proof of explaining why mankind cannot create such entities lies with the deniers at this point. The only way to really deny this possibility (probability in my view unless mankind destroys itself first) is to insist that there is some mystical magic that can only be invested in human beings via means for which there is absolutely no evidence - as per 2. And given that, if evolution could lead to sentient conscious mind I see no reason why a sufficiently advanced sentient being could not create same or better via intelligent design.
5. Therefore, in light of all of the above, I find it likely that some form of advanced intelligence in our universe has created it's own virtual universes with its own sentient beings in it.
Maybe there is better evidence for "sort of woo like telepathy" than there is for "advanced beings in our universe [who] decided to play god and created their own computed universes to observe and/or interact with."
I see no such evidence and no winners of Randi's million bucks. More importantly, other than to posit an informational substrate for the universe which, in theory, could support seemingly supernatural processes, I see no plausible mechanism postulated, analogous to the one I've postulated above for Alien-generated universes, whereby such woo should reasonably be expected to occur and why it is so hard to confirm.
My mind remains open to both possibilties but the former has been subject to repeated falisfications whereas the later is admittedly hard to falsify. If evidence should arise that makes the occurrence of life, especially intelligent life, appear too remotely possible than I would revise my doubts accordingly.
