Here (in no particular order) are the most ridiculous evidences used to me personally to show that the Earth is 6,000 years old or that the Creationist model is correct. If you have any trouble understanding why, then you need to get an education, available at any good school.

1. Geologic column is not found complete in any one place - Proof that Geologists make things up to suit themselves
2. Icthyosaurs fossilised giving birth - Proof that the flood happened, as Icthyosaurs must have died and been buried rapidly
3. Darwin recanted on his deathbed - Proof that even Darwin didn't accept evolution
4. Population growth - Proof that Adam and Eve started the population 6,000 years ago
5. Saturn's rings - Proof that the Solar System cannot be 4.6 Billion Years old
6. Civilisation beginning 5,000 Years ago - Proof that humankind began then
7. Living Fossils - Proof that evolution is wrong
8. Oldest part of Biosphere - Proof that Earth is 6,000 years old

Here are some others from the members of the No Answers in Genesis site:

1. With so little light on the ark (only one window) the animals and people are likely to have slept. Thus, due to them using much less energy they were in need of much less food.
2. After the flood the plants must have "miraculously" grown back. There can be no other explanation.
3. The salt and fresh water fish must have miraculously survived as well
4. People were able to live to vast ages (+200 yrs) in biblical times because themoisture in the firmament reduced the amount of UV radiation reaching the earth and so cancer was virtually unknown.
5. Carnivores were herboivores before the flood
6. Increased Oxygen in preflood atmosphere meant people could live until they were 900 and grow to 10 Ft high
7. Adam and Eve were medium brown (possibly because they were made from dirt), and that is where the races of humans came from
8. Evolution is about the Big Bang
9. Evolution is about the origin of life.
10. Evolution is about "molecules to man".
11. Evolution is about "bacteria to bears".
12. If a new species evolves, the old species must go extinct at once.
13. Humans evolved from monkeys.
14. Humans evolved from apes.
15. Evolution teaches children they are no more than animals.
16. Evolutionists want evolution.
17. Dinosaurs and men were contemporary.
18. All living things evolved by chance.
19. "Social Darwinism" is part of evolutionary theory.
20. Punctuated equillibrium and gradual evolution are mutually exclusive, and cannot both be true.
21. All evolution is the result of natural selection, and every feature of an organism was chosen for its fitness.

any 'I don't see how "such and such" evolved' or 'I can't believe that "such and such" evolved'
