It's a theory not a fact

● Hypothesis: A possible explanation
● Theory: A proposed explanation that is consistent with all available evidence that has been repeatedly tested
● A theory evolves from interpretation of data(facts)
● "Theory" is frequently misunderstood by the general public
● Gravity - Newton and Einstein is "just a theory", but I predict that if you jump from the roof of your house, you will fall.
● The scientific method is a sequence of steps for analyzing the natural world. 

This should help people stop saying things like "Evolution isn't a fact. It's just a theory"
