Bryce Mitchell recently responded to Ilia Topuria, who made fun of his theory that the Earth is flat rather than round. Mitchell challenged Topuria to settle their disagreement through a debate on the topic.'Thug Nasty' is coming off a victory over Said Nurmagomedov at UFC Abu Dhabi. Since that win, he has been seemingly active on social media, discussing various subjects.In a recent Instagram video, Mitchell addressed a statement made by his former rival, Topuria, and shared his thoughts on it:"The champion Ilia Topuria basically calls me a fool for believing that the Earth is flat. When God says that the Earth is flat, and he made the Earth flat, so, Ilia, remember you're not arguing me about flat Earth... you're arguing with God..."He added:"Even though you say you're a Christian, you believe the indoctrination you were taught in school over the word of God. Tell me why, tell me why you don't in the firmament, Ilia?... Since you've been reading so much of your bible, I'd like to have a debate with you about the shape of the earth."Check out Bryce Mitchell's post below: View this post on Instagram Instagram PostWhen Bryce Mitchell talked about his defeat to Ilia TopuriaBryce Mitchell and Ilia Topuria faced off as undefeated fighters at UFC 282 in December 2022. The bout saw Mitchell lose to Topuria via submission in the second round.In an interview after the fight with Fanatics View, 'Thug Nasty' reflected on his first career defeat, saying:"I was really mad, so I didn't really wanna do it again, but then I started thinking how that one really doesn't even count. I understand that it counts on my record, but when I look back at it, I just can't really count that as a win or a loss. It doesn't even count as me going in there. I didn't rehydrate properly... I was cutting weight on medication they say you have to eat with... I didn't even go into the f**king fight being me." [9:31 of the interview]
