There are lots of ways to verify the age of the earth. I do not see what difference it makes what age the earth is. If you want to deny the age of the earth then you have to deny science, not just the theory of evolution. I do not know how people that can barely pass their high school science requirement yet they think they know more about science then a PhD that has studied the subject for 8 years. It would be sort of like going to a doctor and thinking you know more about medicine then he does.
And exactly how is the age of the earth/universe verified? Do you not see the difference in what the word of God tells us, and what evolution(those who take God out of everything) says? Do you know how Creationist determine the age of the earth/universe? If not, it's by tracing the lineage from Adam to Jesus Christ, and this can be done by using God's word (Bible):
*****************************************************************

SUMMARY OF THE TIME FROM ADAM TO JESUS *
* *
* Adam to Abraham .................. 1948 yrs *
* Abraham to Egypt ................. 290 yrs *
* *
* From Egypt to Moses: (X) Let X = 63 63 yrs *
* *
* X = (Kohath to Amram to Moses) *
* *
* Moses to the Exodus .............. 80 yrs *
* Exodus to death Joshua ........... 70 yrs *
* Judges to Samuel ................. 450 yrs (Acts 13:20) *
* Kings of Judah ................... 513 yrs *
* Babylonian Captivity ............. 586 B.C.E. *
* --------------- *
*
Adam to Jesus 4000 yrs *
So, according to God's word Jesus Christ our Lord and Saviour came when the earth/universe was 4,000 years old, it has been 2,000 years since Jesus Christ, so one would conclude that the earth/universe is only 6,000 years old. Millions/Billions of years is a fallacy invented by the Babylonians(Enuma elish-the Babylonians religious text) to take God out of the equation of how we are here, it was here long before Charles Darwin. Have a blessed day.
