Genetic Mental Illness.
Brain Damage.
Stockholm Syndrome/Childhood Indoctrination. (They're the same thing)
Poor/Lack of Proper Education.
BTW... We're not going on "Assumptions" and Carbon 14 dating isn't the only method being used to calculate the age of the known multiverse. There are DOZENS of different fields which all come together with the conclusion that the earth itself is approximately 4.6 billion years old. Astronomy, Physics, Carbon Dating, and so on and so forth...
We KNOW that humans first got to Australia approximately 50,000 years ago... So that means that no matter what, the whole 4000 to 6000 age is NONSENSE.
I'm so very sorry you are mentally ill and can't take the time to do a little research.
