Except they don't tell me the same thing, do they?
I have the Christians telling me one thing, Muslims telling me another, Jews telling me another, you're there telling me something different again...
Why would different religions teach the same things? Why would God send a new Messenger to reveal exactly the same things He revealed before? Why would the needs of humanity in this new age be the same as the needs of humanity 2000 years ago?
Some of what the new Messenger reveals is the same as what the previous Messengers revealed but some of it is new and different teachings and laws which were revealed to suit the needs of humanity who live the age in which the religion was revealed.
So, ya know...
I just figure, "They can't all be right, but they sure as heck fire can all be wrong!"
It is possible that all the religions are wrong, and if there is no God that would be true.
However, if there is a God then it makes sense that at least some of the religions are right or partially right.
For you to say that some of the religions are wrong so all of them must be wrong is the fallacy of jumping to conclusions and the fallacy of hasty generalization.
The truth is a little more complicated and it goes like this. All of the great religions teach the same spiritual truths so in that sense they are all right, but the older religions have been changed and corrupted my man over the centuries so they are no longer as true as they once were. The Baha'i Faith is the only revealed religion that has not been changed and corrupted by man because Baha'u'llah put protections in place to prevent that from happening.
And since NONE of them can provide any actual evidence (no, what you're presented is not evidence), the only thing they all have in common is a reliance on logical fallacies and subjective opinion that they THINK is objective fact.
All religions have evidence, the Messengers who revealed them and the scriptures that were revealed and the historical facts connected with their revelations.
