Assuming There Is a God, Why the God of the Bible of All Gods?

It is by no means self-evident that a God exists. Contested, doubted, also justifiable? Let's say hypothetically, he exists. Why would it be the christian God? Just out of convenience because that's how we were socialized? What about the gods from other religions?

So if God, why this one: arguments and an invitation to discussion.
