Actually the earth is quite young.
As you well know, the evidence of the actual fiat of creation was destroyed in the flood. The evidence the YEC present is chiefly flood evidence.
Although, Polonium Halo's can be considered as evidence of a rapid fromation of the Basalts.
Not to mention that C-14 hasn't met equilibrium as of yet...which it should have if the earth is as old as some claim.
Many say the continents should have eroded by now, that is if the continents are as old as some claim.
Judging from the erosion rate of Niagra falls as it retreats from lake Ontario, the falls are much much younger than the old earthers claim.
The observation of the earth population and population growth also support a recent creation.
We also must not forget the decay of the magnetic field of the earth which STRONGLY indicate a young earth and recent creation along with the recession rate of the moon that would have put it too close to earth a few billion years ago.The low amount of helium in the earth atmosphere and the low level of salt in the ocean also say young earth. Not to mention that the sediments in the ocean would be higher is another example of a young earth. Polystrata trees are also a good example and proof that strata forms quickly and not over millions upon millions of years. The soft sediment deformation of rock strata is a very good indicator of a rapid folding of the pre-hardened rocks and not millions upon millions of years as the continents drifted slowly. The rapid formation of the Grand Canyon when the Hopi and Grand lakes broke through their damns show how it could have been formed in a very short period of time and not millions of years. The Mt St. Helen Volcano and after results PROVED the possibility of quick canyon formation.
Here is a list of other reasons as to why the earth CANT possible be 4.5 BY old.
Personally I haven't investigated each item as I cut and pasted them from somewhere a little while ago. I also don't claim to understand each topic presented in the list. But the point is there is a lot of scientific objection to a 4.5BY old earth or a 16 BY old universe.
1. The amount of dust on the moon's surface - I understand this argument is generally no longer used due to more up to date rates of processes and info. being utilized (i.e. Snelling's article in TEN Tech J)
