By the sun and its morning. ( 2 ) And [by] the moon when it follows it

[The Valkyrie]

If God chose you to be a prophet, who am I to object?
But you lack convincing signs like the Quran, or giving birth to Jesus, you don't have a cane that turns into a snake and your hand doesn't turn white.

The Sura is quite strange for its time. Quite modern? Why would a bedwin Sheppard care about such things?
He didn't abuse kids. Rather defined a new age for them, took them out of the dark ages they used to roam.

Why would I aim at being something as lowly as a prophet?

Aim high with your goals, man.

Anyway, the signs for a prophet as you seem to put them are silly.

1. The Koran isn't a convincing sign. It's a badly written book.
2. Why would I want to give birth to a Mexican?
3. No, I don't have a cane that turns into a snake, but I DO have a Jedi fighter that transforms into a robot. And that Jedi fighter is real. I have physical proof.
4. Of course my hand doesn't turn white. I'm already white. But, given the right conditions, my whole body turns brown.

So, I'll stick with being a deity.

As for the rest. Claims aren't proof.
