The Ethics of Launching Space Out Into the Abyss

My son disagrees that things humans would be able to take them out. There are 2.5 million ants per one human and they are strong. I mean, like that means let's say it takes. half a million to cover your whole body. How many of you think it would take? It's just say if it's 500,000 ants covers your entire body, like they could crawl in your body. That means it's out of every human. What do you think? I think humans still win.
