Reality isn't massively concerned with your agreement or lack thereof. If an entity has been sufficiently defined and has been imbued with mutually exclusive and/or contradictory attributes, it's a fairly simple matter to disprove its existence with nothing more than a single law of classical logic. The law in question is the Law of Non-contradiction. In the propositional calculus, it can be stated simply thus.
¬(P, ¬P)
There are other formulations, but this one serves. It says, in natural language, not(P and not-P), in other words, the propositions P and not-P cannot both be true at the same time. So, what does this mean for well-defined entities? Let's take a look:
Best place to start is the deadly trilemma:
1 John 4:8 (NLT) - "God is love." 1 Corinthians 13:4 (NLT) - "Love is not jealous." Exodus 20:5 (NLT) - "I the LORD thy God am a jealous God"
This entity falls foul of the law of non-contradiction, and therefore does not exist.
Omnipotence: We'll avoid the usual clichéd arguments and just deal with an allegedly omnipotent entity that is foiled by iron chariots.
This entity falls foul of the law of non-contradiction, and therefore does not exist.
Omnibenevolent: This entity allegedly loves us all so much that he wants to see his son (himself) tortured to death for a sin that the perpetrator thereof had no idea he was committing.
Falls foul of the law of non-contradiction and the does not exist.
Omniscient: Can't count the number of legs on an insect and thinks that bats are birds, and that having your livestock shag next to different coloured sticks produces stripy offspring (we'll set aside the fact that omniscience is self-refuting; any entity described as omniscient does not exist).
This entity falls foul of the law of non-contradiction, therefore this entity does not exist.
Creator of all existence: The universe is literally all that exists. The word means 'that which is'. This entity, in order to exist, is contingent upon existence, and is therefore contingent upon the universe, thus cannot be the creator of all existence.
This entity does not exist.
I'd be happy to go into more detail in the above.
There you go, 30,000 gods refuted in one post.
Next mission: World peace!
Whether or not you agree, this is demonstrable and, as I said, trivial, toi anybody who's given the matter a modicum of thought, as opposed to accepting the wibble of others.
It's commonly accepted that you can't prove either a negative nor a non-existence postulate. Unfortunately, it's also wrong, because both operations are fairly straightforward. Indeed, proving the non-existence of imagined entities is something we al;l do on a daily basis, such as when you look out for the car prior to crossing the road.
Your statement is a truism and, like most truisms, isn't actually true. Feel free to disagree. It won't make it any less wrong.
