If, if, if

If humans flew up very high
If the houses were in clouds
If trees were up high in the air
And bugs weren't around

If cars were not invented
And stars lit up the sky
If we could fly instead of drive
And houses were closer than a mile

If there was no gravity
And children knew it all
They wouldn't have to do exams
Like Maths or English or art

If there was no pollution
And birds flew very low
I wouldn't like it much
Cos, where would animals go?
