It might "seem" that way to you, yes. But so what? How things "seem" to you is a reflection of your intelligence (or lack of it) not reality. In fact: cycling helmets were introduced for young children to deal with a very specific problem that adults don't have - their still growing skulls are relatively soft and therefore more vulnerable to low speed falls. And not only is this information something you could have found in seconds with google, it has been cited multiple times in the last few pages of this thread!
Once again: you should at least aim for a minimum standard of post so that you're not simply wasting people's time. For example if you're utterly ignorant, don't use that as an excuse for believing whatever fantasy most appeals to you and then attempting to present that fantasy as a logical argument.
