Why the need to be so condescending. If you feel the need to change someones viewpoint, this way never works.

I apologise if my tone was too strong. But given his tone, its difficult to blame me.

I dont really need to change his point of view, and i doubt he is willing to question it.

One is followed Romans and the Greeks. 

The other is followed by Christians who are from almost all parts of the world.

Jay, you're evading the question. Its not about who follows them but where they came from. Who created the Roman/Greek Gods, wich we could agree arent real? And why is it different from the creation of the one followed by Christians for example?

In theory, either of the partners in a gay relationship can have a child of their own through a surrogate mother. It's just that the child won't be biologically descended from both of them. And I remember reading somewhere about a breakthrough implying that two sperm cells being fused to begin fertilisation would be feasible, but I can't seem to find that at the moment.

And of course, a daughter would do just as well as a son in that regard.

Christianity really became a major religion when it was adopted by Ancient Rome. From there, it spread across Europe. As Rome fell and the former colonies became independent, they stayed Christian, because they couldn't really remember any other system of belief. So, as Europe colonised the rest of the world, the same happened to the people of North and South America and of Africa. Did the Native Americans and Aztecs believe in a Christian god? Do the African tribal religions revere Jesus? Not at all.

Really, the only other place where Jesus features is in Islam, which was largely just an extension of Christianity and Judaism anyway.

How do you know the Roman/Greek Gods were created? How do you know they aren't real?

And even the Roman/Greek Gods are not real, that still doesn't disprove the existence of any God.

That's exactly what he's asking you.

What makes Yahweh any more real than Zeus or Ra or Odin?

To be fair, the idea of a single Creator who has mostly left everything alone for 2000-odd years is more believable than an entire family of bickering gods who throw lightning around and eat each other.

I don't believe it, but it's more believable.

Oh jay... How do i know they arent real? Cause i know thunder is not the result of Zeus rage but of the interaction between particles in the atmosphere for example. Sorry im not really familiar with all the exact processes but its researched and proved. Wich is why we as humans can create a thunder ray aswell.

That actually leads to an interesting logical conclusion. We/humans are Zeus! If the roman gods were a creation of human imagination, why would the other one be real? Certainly something must prove it to not be the same as the Roman/Greek gods? Or you're saying we should believe in the same exact story with a different cover?

You say you are atheist, but you sure give the God story alot of credit/faith, despite obvious examples of the past.
