If there is a creator, so what?

[robvalue]

My stance has always been that it may be possible that some sort of intelligence created our universe/reality. Currently I see no reason to conclude that there is.

But if there is one:

1) We don't know if it still exists
2) We have found no evidence of it within our universe/reality
3) We have no current means to learn anything about things outside our universe/reality, if such a thing is even coherent

My conclusion is that it is entirely irrelevant, unless new evidence emerges. In other words, it makes no practical difference to me if there is a creator.

There's all these arguments trying to establish a generic creator, such as Kalam or intelligent design. Call the creator God if you want, we haven't learnt anything about it just by giving it a title. So if I let your arguments stand, and there is a creator, can you tell me what difference it should make to me?
