I don't know what else to say except look up what a sperm is and look up what an egg is and then say the differences are arbitrary.

I posted a link to a video showing human sperm approaching & trying to pierce a human egg, & OP ignored it.

And in a previous discussion I provided links to pdf textbook on human anatomy and physiology and they ignored that, too.

Not saying there are no differences between sperm and egg ... all I'm saying is the differences exist because only sperm and egg can fuse and create a zygote. If it were the case that two sperm or two eggs could fuse and create a zygote too, then it would mean the differences between sperm and egg are arbitrary and could as easily occur between two eggs or two sperm.
