With the thousands of pieces of pottery depicting dinosaurs & people hunting them & killing them, and the stories of dragons, etc. One could question their co-existance with man. Nearly every culture in the world has historical records, stories, and legends that include dragons. Here is a quote of Marco Polo: "Leaving the city of Yachi, and traveling ten days in a westerly direction, you reach the province of Karazan, which is also the name of the chief city....Here are seen huge serpents, ten paces in length (about 30 feet), and ten spans (about 8 feet) girt of the body. At the fore part, near the head, they have two short legs, having three claws like those of a tiger, with eyes larger than a forepenny loaf (pane da quattro denari) and very glaring."
To me, it just doesn't seem logical that with all of the gases & non-life, etc that matter, energy, amino acids, dna, the intelligence system behind dna (which is an incredible study of it being self replicating, & self correcting) etc all came from a stew of poisonous gases & rocks that were hit by a meteor. The symboitic relationships of the life forms on earth, along with the delicate balance of processes needed for life are proof enough for me of design, and not random chance.
