I would say with most things you can't prove they don't exist.
even if it is likely they don't.
for instance it is highly unlikely a 15 foot man exists.
But you can't prove the 15 foot man doesn't exist, just because you think it's unlikely.
He could live in a jungle or in a cave. Just because no one has seen him doesn't disprove
his existence.
It's like that with many things, aliens, religion,cryptids, etc.

So, you say, they probably (or maybe almost certainly) don't exist and forget about them.  You have enough business doing what you have to do with things that do exist.

Rediculous. Yes you cannot proove a negative this is true.. Double negatives always have problems, but rational people do not need the aggregate to dictate truth by plural reasoning to what they know is true. Some things do not lend themselves to repeatability through demand.

nobody is really interested in proving god 'exist's

all they're interested in is to prove that 'someone else's god don't exist

How can we be so arrogant as to believe that these frail bodies we live in
are perfectly equipped to perceive of all the unknown powers that exist in the universe?

Isn't it rather illogical to think that our limited collection of earthly senses
should be able to perceive of energies, entities and interdimensional physics
that exist elsewhere in the cosmos?

When we start arguing the philosophies of truth and reality,
we start by giving ourselves waaay to much physical credit.

Ya think?

If something want to exist, it will prove by itself. If non exist like to stay out of the existence, don't try to make it Visible, you may be wasting your energy and time.  May be the existence is only for your belief, new belief for a while.  It can be your own fantasy world not all.

I can "prove" a statement false by providing  a counter-example -- "All  swans are white" is falsified by producing a black swan.  "God is omnibeneficient" was falsified at Dachau.  "God is omnipotent" by asking if there is anything God cannot do, since if the answer is yes then God cannot do that thing and if the answer is no then there is doing something he cannot do we can put  on a list of things he can't do (self-referetial contradiction).

Does Sasquatch exist is easily proved by producing one, but there is no counterexample (failure to produce one when by now we would normally expect it is strong counter-evidence but he could always be just over the next hill..  That there is no  historical record of any Jesus Christ from non-Christian centuries until over a century after his presumed existence, when in fact there were enough authors of the period who we would expect would have mentioned him but didn't is pretty good  reason to  think he didn't really exist, but not proof.  (This is the biggest hypocrisy in Christian apologetics -- when push comes to it they always end up  with, ":You can't prove otherwise.")

Disproving something is as simple as proving the opposite. Frank Merton's swan analogy demonstrates this method perfectly. Proving something's nonexistence is not only largely impossible, but it is a waste of time when the opposite is usually simpler. If someone says "chupacabra exists" but can't show it, conclusive proof of its nonexistence is not required as the lack of proof supporting it is lacking.

Ripped from a corpse, so freshly dead,
Together with our hellish hate,
We'll burn you all, that is your fate!
