Aliens aside, if there was a pre-flood Earth then why isn't there more clear and present evidence? I want to believe in ancient human civilizations but the more I read into it, the more unlikely it seems. Some conspiracies say they were Phoenician-tier at the least and sea faring. Capable of Atlantic travel. If that's the case, why don't we have evidence of food exchange?

Spain's entry into the new world saw tomatoes and potatoes (to say the least) spread throughout Europe within 50 years. Staple crop within 80. Presuming an ancient civilization, were these colonies wholly autonomous or was there still travel? You wouldn't be able to prop up a civilization without introducing the domestic animals your society knows. No wild pigs or cows until Columbus' second voyage.

Cocaine in the bodies of dead Pharaos. 

Besides, Flood / Deluge is mentioned in MANY different cultures/religions/mythologies. It is the normal thing to assume that that shit wasn't fabricated. 'Science' is an idol.

Do you have more examples of cross-contamination like that? I'll look up the cocaine in Pharaos hook. While I'm researching this I figured Vikings would've brought material back, but most of them setup permanent settlements. Less resources in the North along with more combative tribes meant less trade. The great storehouses in Newfoundland didn't have trace none of native NA crops.
