God made Phlegm? Why?

There is no God to hear your prayer
This earthen sod and natures lair
is all there is. For truth and reason;
the world and its wonders are enough.

Faith needs no proof yet brazenly questions science!
It never made a building or fixed a bad appliance.
WE create the gods and blindly hold them dear
Religion? It is the child of hope and fear
Teaching the unknowable to the ignorant
It makes its flocks intolerant
It holds their thoughts in chains
Till nought but faith remains

Good is for goodness sake and not for God's!
Don't heed the siren voice of priests and demi-gods
Wonder about the earth you children of the stars
Mans voygaging discovery, the moon , the sun, the stars
Be a dissatisfied thinker not a satisfied fool
The truth cannot injure you! Make this your rule!
Unreason makes you blind but reason makes you see
Do something to deserve the fact you top the living tree

Dont fetter your thoughts with those of ancient men
Dont waste all your life on some hoped for heaven
Science plants your feet in reasoned experience
It keeps your beliefs proportioned to evidence
Faith is blind. It cannot meet these tests
Will you sleep with the ancients while science never rests?
And if you find yourself scared and to religion must fly
Just seek an answer from your "Lord" - God made phlegm? Why?
