Why cant humans fly?

Question

Seriously!

Answer 1

This is for the mass of human beings. This mass of human beings bounds human to stay towards the gravity, towards the earth. Human can never be as light as birds. So human cant fly like birds,

And another the unique shaped wings of birds can never be for human beings even it cannot be for human beings even by evolution.

THANKS

Answer 2

We are to heavy to float in air.

Answer 3

We have no proper way to propel ourselves upwards, and we are too heavy.

Birds, for example, have hollow bones and pockets of air in their bodies to make them light. They also use their wings to provide them with upward motion, because the wings and feathers push against the air. We can flap our arms, but we will not displace enough air to get us airborne.

Answer 4

We can. Jet planes, some of the newer gliders, rockets, magic, and prosthetic wings will work for most people. :D

Answer 5

I am not a biology expert but I think it is because we don't have wings. I hope that helped!

Answer 6

We're too heavy--our bones aren't hollow like birds

We're not aerodynamic at all--our bodies aren't shaped like a foil.

Answer 7

Hahahaha!

Wait. Are you serious?!

Because it's physically impossible! Duh!

Common sense smarty!

Answer 8

Wow! Am I the only one who notices those flying machines moving through the sky?  Humans can fly, I just got off a plane.

As for why we can't fly under our own strength it's simple.  We're too heavy.  We don't have the strength to generate the lift necessary to get ourselves airborne.

Answer 9

because we dont have wings but i know you can use meditaion or dark magic like "chris angel" he flies

Answer 10

No wings + too heavy = no flying

Penguins have wings, but still can't fly because they're too heavy.

Answer 11

We aren't designed to fly.

Answer 12

We are terrestrial bipeds.  Humans evolved that way because there is no advantage to flying.  Humans would not look very much as they do now if their evolution had included flying.  I doubt we would be asking questions and answering them.
