[...]This is still a silly thread because whether you believe in God and a higher meaning to life, or feel that

This is still a silly statement. You seem to be oblivious or ignorant that this thread is about the fall of theism and its implications for the future of society and mankind. You only joined because someone noted that no non-atheists opined so far but only to not give your opinion on the suject by pointing out how silly the discussion is.

But still if it were a discussion about wether theism or atheism makes more sense, it would not be silly! Futile maybe, silly no. Topic recognition skills: FAIL!

Science still can't agree on the nature of the universe which is why we have so many theories to explain the physical universe. String theory being the latest in vogue theory to explain everything, which requires us to except alternate dimensions. We can't prove it yet, but it has a growing following.

If science can't explain everything, so what? That doesn't mean that there is justification to make shit up out of thin air. What if there are different approaches to unify all occuring phenomena in the materialistic universe? Did Einstein proof Newton wrong? (Hint: no). Even if science has not all the answers yet (or might never have them), that does not change how we perceive and understand the universe so far if we adhere to a coherent and consistent explanation. And, yes, it might change substantially over the course of a lifetime and still be consistent with all we had known before!

You are operating on faith that you are right, because it can't be proven one way or the other.

Everything you do, think or belief requires a leap of faith, so what? The best you can do (and thankfully for you, your brain does it automatically most of the time) is go with the probabilities. And the physical universe is really much more probable than magic! Sorry, if your old buddies, the philosophers of long past, were not vested with all the science and other tools to get a better estimation of what is actually going on. They might have gotten some things right but they were (sometimes admittedly) just sitting in a cave and looking at the shadows.

But btw: string theory has been around for years now and is not the latest in vogue, what you describe as alternate dimensions are actually dimensions as in height, width or time. What you probably are referring to is the multiverse theory, which features what one might call classic sci-fi alternate dimensions (realities, i.e. universes). Sorry, renaissance man, remember?
