New to this

I am new to this, I had to look up what unconventional is. 

What poetry is unconventional? 

Unfamiliar is a synonym of unconventional, if so then what is unfamiliar to humankind...everything? 

How are we so sure? 

You tell me "Science" yet I still doubt you. 

How can I be sure of anything? 

This is just a poem it doesn’t have to rhyme or sing, so tell me what you think.
