Why Humans Cannot Fly

Here is the reason why humans cannot fly, according to the 7-year-old:

If humans can fly, there would be no need for cement or asphalted roads.

If there are no cement or asphalted roads, the grounds will be filled with grasses, weeds and other vegetation.

If the grounds are filled with grasses and weeds, there would be lots of insects.

Soon, insects will take over the world, and wipe out the humans.

Therefore, humans cannot fly.
