I probably just have a really bad grasp on how genetics work, but if human eggs already have an X chromosome plus all the other necessary genes needed to combine with another haploid cell, why can’t 2 eggs just combine with each other to make an XX zygote?

Yes, each the egg and sperm carry half the DNA sequence to produce an offspring. However they aren’t the same. They are the opposite piece of the puzzle. Like having 2 left shoes don’t make a complete pair. That’s not to say with some intervention science may be able to flip and mirror one of those left shoes to effectively create a right shoe. For now, 2 lefts don’t make a pair.
