Because God knew we will invent aeroplane! :D
We do fly, en masse, thousands of times every day. Our technology overcomes what our biology doesn't provide...yet again. Isn't science wonderful.
You got wings yet
They can barely drive .. Never mind fly!
Apart from being biologically unable to do it, why can't humans fly?
The animals that CAN fly have adapted to over time. It's all about evolutionary biology.
Biggest reasons why we can't - Physics and Aerodynamics.
All of these things and much more
are with in your reach.
Believe and Receive.
Who says they can't fly? We have planes, parasails, and windsuits. We can also fly figuartively.
