I am neither an Old Earth Creationist nor a Young Earth Creationist. Nor do I lean to the Gosse Omphalus Hypothesis which says that the universe only looks old, it could have been created last Thursday.
I'm sorry, but I have no patience for such an argument. What does "looks old" mean? When Adam was created with an adult body did he "look old?" When a fully formed universe was created 5770 years ago did it "look old?" It could not, because there was nothing "old" for anything to look like! Things only began "looking old" once the universe had been in existence long enough for things to age. Furthermore, the remark about "last thrsday" is completely uncalled for. It assumes the existence of "false memories," which is something anti-literalists have created whole cloth out of their imaginations in order to insist that Adam could not have been created as an adult (because he would allegedly have "remembered being a child").
The main thrust of your argument (that nothing matters except J*sus) is the cause of the whole problem, and it is why chr*stianity is a collapsing house of cards. But don't worry . . . the real Messiah will be here soon!
And yes, I realize that you are not Christian. And I am very sure when you meet the Messiah, you will know Who He IS.
Also, I mentioned the Gosse Omphalus Hypothesis for comparison purposes only.
Basically it posits that God said He created the universe 6,000 years ago (by our space/time coordinates) and therefore that is the truth of the matter. If it looks old, it is because He created it that way.
