That's a really bad argument, because the Hebrew version of the Deluge is just a plagiarized copy of older written stories, and the Hebrew version doesn't even get it right. In fact, it contradicts itself. It says one pair of each animal was taken, then later it says 5 pairs of clean animals and 2 pairs of unclean animals (clean animals are fit for sacrifice, unclean animals are not). So, which was it? Was it one pair of all animals or was it 5 pairs of clean animals and 2 pairs of unclean animals? It says it rained for 40 days/nights, then the flood waters were on the face of the Earth for 40 days/nights and then the waters receded after 40 days/nights for a total of 120 days. Then it says the flood lasted 365 days. When does 120 days = 365 days? It's ridiculous to rely on a story that contradicts itself and is heavily flawed, not to mention written thousands of years after a few dozen such stories already existed. Nobody cares if they lied. We saw the Nephilim there (the descendants of Anak come from the Nephilim). That's called a parenthetical. Someone added that in later for clarification. The simple fact is the descendants of Anak are from the Nephilim. They may not have been in the town where the spies were (and thus the spies lied), but they were still in the area nonetheless. Fail. Joshua 15:13 Caleb son of Jephunneh was assigned Kiriath Arba (that is Hebron) within the tribe of Judah, according to the Lord’s instructions to Joshua. (Arba was the father of Anak.) 15:14 Caleb drove out from there three Anakites – Sheshai, Ahiman, and Talmai, descendants of Anak. Double fail. Joshua 21:9 They assigned from the tribes of Judah and Simeon the cities listed below. 21:10 They were assigned to the Kohathite clans of the Levites who were descendants of Aaron, for the first lot belonged to them. 21:11 They assigned them Kiriath Arba (Arba was the father of Anak), that is, Hebron, in the hill country of Judah, along with its surrounding grazing areas. Triple fail. Deuteronomy 1:26 You were not willing to go up, however, but instead rebelled against the Lord your God. 1:27 You complained among yourselves privately and said, “Because the Lord hates us he brought us from Egypt to deliver us over to the Amorites so they could destroy us! 1:28 What is going to happen to us? Our brothers have drained away our courage by describing people who are more numerous and taller than we are, and great cities whose defenses appear to be as high as heaven itself! Moreover, they said they saw Anakites there.” Quadruple fail. “the sons of the Anakim.” The Anakites were giant people (Num 13:33; Deut 2:10, 21; 9:2) descended from a certain Anak whose own forefather Arba founded the city of Kiriath Arba, i.e., Hebron (Josh 21:11). Quintuple fail. I hope you're not a christian, because that would be pretty sad to get beat up by an atheist like me.
