@jinx25:
It is a faith based belief that because xyz is decaying at abc it has always been doing that, which if one believes Noahs flood, it hasnt.
Actually, assuming that radioactive decay is always occurring at the same rate is a logical assumption, unless you have counter-evidence. And we have no counter-evidence. So we can assume it has always decayed at the same rate.
Pouring a lot of water over a radioactive substance, like it happened at the Great Flood, is not going to change the rate at which radioactive decay occurs.
Theres no law that says things HAVE to start at the top of the decay chain too, its BLIND FAITH there was no daughter element present in sample to begin with.
Of course, it would be conceivable that radioactive decay did not start until some years ago, but there's no evidence for it, so assuming it would be illogical.
And you're right, there's no law that states things have to start at the top of the decay chain. But then again, there doesn't have to. If scientists had to formulate laws just to rule out every conceivable impossibility, they would spend more time doing just this and almost no time researching.
To the person who has FAITH in 'billions and billions' there is EMPIRICAL evidence AGAINST it.
No, not really. What you gave us were counter-arguments, but without evidence.
What no one has mentioned yet, at least as far as I can tell, is the fact that we can observe stars that are millions, if not billions of light years away from us. As we know, the speed of light is limited (hence where the name 'light year' comes from), so we could never see these stars if their light didn't have enough time to reach us.
