Shameless plug

You don't need to be conscious of time to experience it, and dinosaurs of course experienced time. When one thing happens and then another thing happens, an animal realizes they did not happen at the same time nor does he mix up the order of events.

Besides, it's the tree falling in the woods. Regardless of presence, it causes vibrations in the air that qualify as sound whether or not there's an ear around to catch it.

Still, much as I lack knowledge about the specifics of Big Bang theory, I disagree that the existence of God can be proven scientifically. For one thing, theory is theory - it's not proven fact that is claimed to rule out everything else possible. For another, as the human mind can't truly understand infinity, I don't believe we're equipped to speculate on what could and would happen in the absence of time and space. Lastly, and probably most importantly, the failure to answer a question does not prove the answer must be God. To an objective and logical mind, the answer is as much God as it is aliens, nothing and magic.
