I really really don't support that the idea of finding God's name on an egg would make you believe.
But, I do believe in the idea of making someone believe using the Bible, Qur'an, or the Torah.
Stuff that are said in the Qur'an like, how it feels like in space, what stars look like when they explode, layers of the atmosphere.
All these and more are mentioned in the Qur'an(keeping in mind that that was more than thousands of years ago.).
That would make me believe.
Not god's name on an egg.
