Actually I worded that wrong. First though, there's a theory gaining ground about creation, earth is 6000 years old, no it's not it's 13.5 billion years old and we have the archeology to prove it! As it turns out, both schools of thought could be true simultaneously.
Imagine the whole universe, space and time, all the planets come into being like a balloon. Everyone knows the universe is expanding, right? And Einstein figured out that time and space are connected. When one speaks of time, he speaks of space and vice versa. Modern scientists have calculated and measured that our universe is expanding at the same rate that time does. So, space-time.
So there's our balloon universe sitting there and expanding all the time. Now, people are able to look backward in time through archeology and such, but we are unable to see into the future.
As the theory goes, creation is at the inlet of the balloon, and all of heaven (being outside of time/balloon) look forward into the universe and from their perspective, creation took 6 24 hour days...but we're at the tip of the expanding balloon looking backwards, so it works out to 13 or 14 billion years from our perspective.
The expansion of space affects space and tweaks it somehow to allow this phenomenon to be. I admit I do not fully understand it, I'm no scientist, but I can visualize how it could work by the balloon illustration. And in fact scripture does talk about space being stretched and rolled up like a scroll and stuff so it may well be trueish.
