1. Small asteroids have hit the earth repeatedly during your 14 years here. Your still here, aren't you?? An asteroid wouldn't have had to have wiped out all life, just changed things enough that one type of animal was no longer adapted to life on earth. Some models use climate change resulting from dust from an asteroid to explain dino die off.
Also...Not every dinosaur died because of the impact. Many other natural causes led to the demise of the specific fossil animals we find.
2. Go to the library and find a good book on Geology and evaluate the evidence carefully. I don't care if you don't agree with me, all I ask is an honest look at the evidence.
3. The grand canyon shows progression of the species and types of animals buried in it's many layers. We don't find cows or pigs or cats or sheep or other mamals in say Jurassic rock. We find very primitive animals in Cambrian era Rock. We find no animals of any types of rock that date, say, 1 billion years old.
also...
Ten million plus species of plants and animals live on our planet and we know that 98% of all previous species are now extinct. How did six people care for ten million species, feeding them, removing waste, etc.
Also...
Egypt, India, China, etc. Had developed civilizations in 2258 B.C. and they quite nicely missed the flood. How could it have been a worldwide flood if the Chinese didn't even notice.
Also...
It is beyond the load bearing strength of wood to build a boat 450 feet long. Impossible no matter what type of wood you use.
Also...
Genetics shows that certain groups such as the aboriginees (being Austrailian you can aprreciate this) are probably 35,000-40,000 years "seperated" from other humans. In other words they are fully human but it would have taken a long time for Genetic drift to have given them the Genetic traits they now posess.
4. I love popcorn.
