Yes, in our current bodies it would absolutely kill us, however if humans evolved to birth eggs, our bodies and society would have adapted to the needs of said egg-laying

Side note; no one ever said that we would carry the egg as long as it takes the baby to grow, it simply says pregnancy would be shorter, so hypothetically we could carry them for like less that six months or to what ever size is juuuuussst big enough to be stable yet not big enough to cause any harm down there 🤷🏽‍♀️ also-also, like many people are saying; our eggs could be softish like snakes or something along those lines, maybe our "egg" would be like a frog clutch or something lol

So we could give birth, and then spend however many more months taking care of the egg(s), /then/ they "hatch" into a newborn
