Is it possible that same god has taken multiple births?

My BF is Hindu and I’m Christian,

I’m not Indian so I had no idea about Hindu stories until my BF told me about them.

He explained the idea of a god coming to earth multiple times in different forms.

but I was curious why that god only came to India and not any other part of the world, same with islam and christianity, they only stayed in one place

it got me thinking, is it possible that Jesus, Mohammed, Buddah , Krishna, are all the same ?

could all of them be the same god?

what you call krishna and i call jesus, they’re just different names, god could have a completely different name or not have a name at all.

Maybe this is above hinduism and christianity
