Can anyone provide an argument for a necessary being?

[Rampant.A.I.]

I like that. I often point out the KCA being used by Christian apologists is nonsensical given the argument seems designed with a "insert specific creator deity and dogma here" slot, but there is also an intellectual leap required between <First Cause> and <Eternal> <Corporeal> <Deity>

I've seen the classical arguments, but every argument for a necessary being seems like an appeal to ignorance.

An unfalsifiable premise doesn't seem rational. Perhaps this is the reason I have problems with ontological arguments: they all seem to be appeals to ignorance, with a deus ex thrown in as the explanation.

So my challenge is: can anyone provide a cogent and compelling argument for a necessary being?

Why we can't we contemplate a necessary being without concluding it exists, without resulting to the same appeals to ignorance that resulted in Thor, God of Thunder and Lightning?

How would a being or entity be necessary in the absence of a plausible natural explanation?

It is foolish word play. There is no coherent argument.

[Neo-Scholastic]

It may be wise to step back and relook at what traits a necessary being would have. A good working definition would be that which must be logically prior to the existence of all things and on which all things depend for their continued existence. Does that work?

Finally, it is not acceptable advise to a philosopher to suggest that because a particular idea is difficult to understand that it is best to not think about it. This is medieval thinking, my friend. I prefer the open and unconstrained pursuit of knowledge of ancient Grecian times or our own age that is finally once again free from oppressive dogmatism and stifling conservatism. We can say here and now whatever pleases our minds and have no fear of being tortured or censured for our thoughts. Let us follow them wherever they may lead, turning here and there as necessary to follow always after that elusive and beautiful creature, Truth.
