I didn’t respond to the things you said initially because I made the mistake of throwing too many bits of information at you at once and that made it complicated to keep track of everything. So here are my responses:

Evolution put the testicles between the legs to separate it from the heat of the internal organs that would’ve been damaging to the sperm. No evolutionist claims that this is perfect design. Testicles between the legs is stupid design. If you disagree with that then you’ve probably never been hit in the nuts or gotten into a fight and learned how vulnerable you are. Men in sports wear athletic cups for this reason.

Now if you’re wondering why evolution didn’t put the testicles in the rib cage and create more hardy sperm, that is something natural selection answers. It’s likely that, as the testicles of some animals descended toward the legs, their ability to reproduce and/or survive improved. My best guess is that the amount of energy it would take to produce hardy sperm that are resistant to the heat of the internal organs lowers chances of survival and reproduction. Think about a woman’s menstruation cycle and the amount of energy they spend each month: the period cramps and moodiness. Are women as efficient during that time of the month? No. However, if it didn’t take more energy to produce, then the hardy sperm likely would take longer to make which is also a disadvantage. The animal with the testicles between its legs could have sperm readily available whenever the opportunity to reproduce came (e.g. female is in heat). Female’s eggs are not in the rib cage but they are still created internally. They create more hardy eggs but they’re not always ready to reproduce like men are. All animal reproduction is dependent on the readiness of those eggs. The amount of time it takes to produce the eggs was determined by natural selection for survival. A female that produced eggs faster would have created offspring that were less likely to survive. But a female that produced eggs slower would have not found a partner that would stick around to protect her during pregnancy. The male with testicles between its legs that is ready to provide sperm when it comes across a ready female is the one that is going to pass down its genes more often than the one whose testicles are in his lower abdomen. So over thousands of years, the animals with testicles that slowly traveled down to a cooler region, had a slight advantage over the ones that did not. This continued until eventually the testicles ended up between the legs. So the testicles being in that stupid spot is because of efficiency and availability in sperm production. But that is not intelligent design. Evolution can only make do with what it has and it doesn’t mean that it’ll lead to something perfect. Natural selection just means that the traits that improve the ability to survive will be gradually passed down while the traits that harm ability to survive gradually disappear. If male testicles started to venture back toward the adbomen, their ability to reproduce will be hindered and natural selection would eliminate it.

Regarding the flightless birds, the answer is simple. For ostriches, the environment that they ended up living in provided little to no benefits for flight. So as the birds genetics slowly changed, the birds with slightly more powerful legs and heavier bodies had an advantage in survival over other birds that could fly. After thousands of years, the birds with stronger legs that cannot fly are what remains. Flight requires a lot of energy and producing capable wings also requires a lot of energy so natural selection eliminated the inefficiency.

With the blind mole rats, they had use for eyes at some point but natural selection provided survival advantages to the animals that did not waste energy producing efficient eye sight.

Evolution does not create something new out of nothing. It can only gradually adapt what it already has to something that can improve survival.

Now can you provide your evidence of gods existence outside of this reality?
