Your understanding is irrelevant as the fact that each religion mutually exclusive according to it's own views not some view you impose upon it.
Irrelevant point dependent on your opinion, nothing more

So what? All you have done is filter all religions from your own religion's point of view. This does not create a fact.
I wouldn't be so hasty to judge.
Fact is each of these religions did come successively historically not simultaneously which supports the view of progressively revealed religion according to each age.
Next, another fact is that in each of these religions, the previous religion and Prophet/ Educator is accepted and confirmed as true.
Next, in each of these religions are prophecies about the next Educator to appear once again supporting that each age has its own teachings and Messenger.
Just rebuttal and denial does not disprove these facts. Check history and you will find all that I am stating is true about the historical progressive appearance of each religion, that they confirm the previous religion is true and prophesy the next Messenger to come. Even Muslims too await the Mahdi and return of Christ.
These are facts of history without any need of referring to my own religion. This image is just an example. The dates are approximate but progressive. You can consult any Encyclopedia to confirm these facts.
