Again, I gotta ask

...is it irrational to believe in God and follow science?

No, we have the mental capacity to utilise the tool that is called "logic". It is not something that exists independently. Also, the question you asked me, which I have put in italics, is so ridiculous given the extremely limited (yes, this is the truth) knowledge humans have of the universe, coupled with the inability to escape culture, and the reality it creates. I don't know much regarding the beginnings of the universe. It happened a long time ago, and I was not there to see it. Maybe sometime in the future people will develop a method to answer all these questions, but it ain't happening anytime soon, and quite frankly whatever answer I could provide you would be an assumption (more or less baseless, and probabyl proven wrong eventually).

You'd be suprised how many people think otherwise to promote their agenda. Heck, the most of important scientists during the 18th-21st century were either theists or deists

Eh, depends on who's theory.

Really, normally I've seen the universe starting off as a singularity that is infinitly dense. 

Which you could argue means there was no space or time as we know it.

Hence the importance places on other dimensions we can't perceive or detect yet.

Still we won't know anything for sure... for a loooooong time.

Hell we don't even know if we live in an open or closed universe yet.

Hmm. I don't know. I suppose it would be like someone saying that an object is falling upwards. It doesn't make any sense to me. The universe is virtually infinite. There are many things that we don't know. It seems to me that putting a big stamp with the word GOD in it all is kinda silly.

I don't reject the POSSIBILITY of a god. What I reject fully is religion.

It seems you are ignoring what i am meaning. Regardless, we have the ability to understand, discern and use logic. This is my whole point, that the universe would not exist without intelligence. Space, time, and gravity does not possess intelligence or the ability to use Logic in and of themselves. The Universe and life cannot begin without it.

Science will continue to develop using new methods and new tools. Some scientists have tried to take God out of the equation, but in the reality if we were living in a universe without an intelligent being it would be a complete contradiction. Yes there are countless theories and possibilities that people will claim, but honestly IMO the most logical one will always be that an intelligent being designed our universe the way it is with order and gave us the ability to use logic in our understanding.

Your point is quite frankly ridiculous. Why would the universe not exist without "intelligence"? I don't see how anything you said points to the necessity of intelligence for the universe or life to exist. Intelligence is a mere trait that has become very developed in humans.

Regarding your second paragraph, seems to me like your basic argument is "I want things to be this way" and if facts contradict this view you automatically label them as "illogical" or "contradictory".

Something else I wanted to add. This may not be the case with all, but from my experience it seems that many individuals who think the idea of a higher being "God" is just totally strange and ridiculous is very much based in what their perception of "God" would be. They can't understand why a "higher being" would exist and why God would go to the trouble of creating the universe, life, ect. and what the sense is in a higher being existing. I think partly they also fear the existence of such a being with so much power.
Maybe they percieve God as some old bearded man in a white robe sitting in a chair in the clouds. Which is only a picture man has given, which Im sure is far from accurate. I think a lot of it has to do with how you percieve who this higher being is. I think the unkown is scary to some people and they dont want to believe such a being could possibly exist, but IMO it couldnt be more evident that such a vastly powerful being does exist.

Really? And do you have any way to back this up? My glasses must be dirty or something, 'cause I'm having trouble seeing this oh so obvious thing you describe.

Also, I'm sure you yourself find it scary that such a being DOESN'T exist, and this post is just the surfacing of your own frustration.

So there has to be an intelligent designer because there is intelligence? Wow, that's a ridiculous claim... 

And how did this intelligent designer came into being? Was there intelligence before? o.ô

Intelligence is something natural... It's nothing mystical!
