You do, implicitly. See above. You are always appealing to what always or never happens, even if it's in an indirect way.
Very indirect. We have very good reasons for thinking that what anatomical equipment males have will not let them become pregnant. But, the fact is, it won't. And that is the explanation of why no males have ever been pregnant. Never mind why we believe it is true. It is true. And that is why it is physically impossible for males to become pregnant. In other words, the proposition that males can become pregnant, and the proposition that males lack the physical equipment to become pregnant are logically incompatible. But
why we think that those two propositions are true is a different matter. If then, If P and Q are incompatible, why we believe P is true, and why we believe that Q is true, is irrelevant. The fact is that P and Q are incompatible. So, since it is a true that male physical equipment is incompatible with male pregnancy, that is why males cannot become pregnant. Our evidence that male physical equipment is incompatible with male pregnancy has nothing to do with the fact that those two propositions are incompatible, and so that is why males cannot become pregnant.
