That certification of hadiths your talking about follows certain steps. Bukhari, tirmidhi, etc didn’t just verify those hadiths were sahih out of nowhere.
To certify a Hadith, it has to fulfill 5 conditions. The first one is, it has to have a strong lineage of narration. Then is has to be from a narrator who is known for his honesty. Also they need to be know for great accuracy when recalling things. The Hadith also cannot contradict other hadiths which have a stronger chain of narration.
There’s no other historical evidence in the world which goes through so much scrutiny before its accepted as authentic.
Also the only reason you don’t like allah and prefer the idea of a Christian god is because humans, generally speaking, don’t like being held accountable. Well, it will happen.
And what do you mean when you say isa as was the last prophet? Are you using biblical text to confirm this or something?
No, i was kidding lmao i don't believe in any abrahamic prophets since i don't follow any of these religions..
