You don't strengthen your argument by trying to excuse the ignorance of the created when compared to the Word of the Omniscient Creator.
Btw, it isn't an assumption. Proof has to be proven by truth. The origin is laid out in the inspired Scriptures. It has not been proven wrong. God has said that man will be judged by the words contained in His inspired Word, and everything necessary for man to pass that test is provided and recorded from the beginning. There have been men who defied and rejected what He has told them from the beginning of time. Nothing has changed. Men still are trying to gather evidence with which to prove Him wrong, and with all of their "acquisition of knowledge", they are no closer now than then to doing so.
Even the Christ, the Son of God, bowed to the Will of God the Father in Heaven. He came to earth, and fulfilled the Father's Will. Who is man whom He created in His image that he should reject Him and call Him a liar?!
Which one? Odin? The Great Spirit?
And is this the Omniscient Creator that planted pre-aged "fossils" just to laugh at his (lower-case "h" on purpose) silly creation as they try to devine his trick.
