No, you would have to show evidence of God himself.
It is essentially impossible to find
undeniable (not that last word, its important) proof of God within the natural world. I absolutely believe in God, but God made the world full of processes, made it to function as one big unit. That these systems work can be said to be a marvel, a very improbable occurance, etc. However, it is not irrefutable proof of God.
Secondly, you are confusing proof of a young earth with proof of God. Most Christians accept that the earth is NOT young. The young earth theory was fairly common prior to advent of science as we know it, but it was something assumed to be true. Only a few scholars would state firmly that they knew absolutely what was meant by Genesis creation story. The most common absolute statements were along the the lines of "we don't know what God's day is", etc.
It was only in very recent times that this idea that Genesis HAS to mean the earth was created in 6 revolutions of the Earth began to resurge. And, you have to ask yourself why, given the perponderance of evidence to the contrary those folks, who were NOT within the scientific community, would suddenly claim that all science is just wrong.
The answer lies not within Christianity, but in the effect of these teachings. Christ teaches us to represent the truth, not pass on lies. I know these things Creationists websites, etc try to declare to be false. Not simply believe, but KNOW, have seen the irrefutable proof. Claiming it does not exist does not make that claim valid. Sorry.
