We observe a history in the Earth, not maturity. Here is what one pastor said of Phillip Henry Gosse's book "Omphalos" which put forward the same idea you are.
Shall I tell you the truth? It is best. Your book is the first that ever made me doubt, and I fear it will make hundreds do so. Your book tends to prove this that if we accept the fact of absolute creation, God becomes Deus quidam deceptor [God who is sometimes a deceiver]. I do not mean merely in the case of fossils which pretend to be the bones of dead animals; but in the one single case of your newly created scars on the pandanus trunk, your newly created Adam's navel, you make God tell a lie. It is not my reason, but my conscience which revolts here... I cannot... believe that God has written on the rocks one enormous and superfluous lie for all mankind." --Charles Kingsley
