As others have said

Your first point is useless, as you are saying the people who believe in something think they saw something.

The second point is the same as the first

The third point is an interesting point but they hinge on the idea that he really died and was really resurrected when even if you accept the first two points there are many other possible interpretations.

1. he wasn’t resurrected in the sense of died and was reborn but instead it was a spiritual awakening where he meditated in a cave and returned as a spiritual leader

2. he wasn’t really dead but was instead in some form of coma

3. he sustained an injury that normally would kill a person but was able to shortly recover before dying for real 40 days later

4. it wasn’t him who supposedly came back but someone imitating him

5. it wasn’t really him who was crucified and was instead someone who pretended to be Jesus to spare him

6. he did really die and his followers made up the story to make him seem larger and help spread his teachings

And those are just off the top of my head in a few minutes. If you want to have faith there is nothing wrong with that but considering the utter lack of tangible evidence you aren’t going to convert anyone.
