The traditional theological argument against the existence of many Gods, assuming that one God does exsist is the following.

Once again it is proved , in my opinion, that philosophy, theology and similar stuff are nothing more than common sense "wrapped" by difficult words.

The point is that common sense is often deceiving

Our intuition claims that infinite must be exclusive
but Cantor proved that various degrees of "infinite" are consistent
Obviuosly he was referring to math entities however it proves , in my opinion that the classic theological argument again the existence of many Gods is wrong
or better that only science can cast some light on the mistery of our existence
