Christians, what is your VERY BEST arguments for the existence of God?

[ib.me.ub]

I was reading all of this and was just wondering why we argue points that we know nothing about, in terms of both arguments.

Ok, so we believe there is a God for example, but it is inconcievable to determine how an entitiy/mass such as this would/could work at the present point in human evolution. It is beyond any possible human comprehension at the present point in time.

Then, we all think the Universe started at a singular point, but once again it inconceivable to determine that this is what actually happened or how it actually works at the present point in human evolution. It is beyond any possible human comprehension at the present point in time.

So, until we know anything for certain, how can we argue the point. Really, we haven't come very far in terms of evolution!! It's all well and good to say 'but look what we have done', 'look at what we do understand', but in the context of actual knowledge we understand very little.

So, I pose the question, What is the point of arguing about things that are far from actual understanding?
