Your first bullet is a glaring false dichotomy. You present two options when there are innumerable other possible options. The most likely is that the first sexual reproduction was probably
monoecious like many plants, or hermaphroditic animals, able to reproduces alone or with exchanging genetic materials, having both male and female reproductive organs. The common

"Debate is an art form. It is about the winning of arguments. It is not about the discovery of truth. There are certain rules and procedures to debate that really have nothing to do with establishing fact ” which creationists have mastered. Some of those rules are: never say anything positive about your own position because it can be attacked, but chip away at what appear to be the weaknesses in your opponent's position. They are good at that. I don't think I could beat the creationists at debate. I can tie them. But in courtrooms they are terrible, because in courtrooms you cannot give speeches. In a courtroom you have to answer direct questions about the positive status of your belief. We destroyed them in Arkansas. On the second day of the two-week trial we had our victory party!"
