Here, I'll do you the favor of giving you a few more Google 
results with hopes that you'll start developing a mental model 
behind what the definition of assertion is:

Google itself: "state a fact or belief confidently and forcefully"

http://dictionary.reference.com/browse/assert: "to state with 
assurance, confidence, or force; state strongly or positively; 
affirm"

http://www.merriam-webster.com/dictionary/assert: "to state 
(something) in a strong and definite way"

http://www.thefreedictionary.com/assert: "To state or express 
positively; affirm"

http://www.oxforddictionaries.com/us/definition/american_english/assert: 
"State a fact or belief confidently and forcefully"

http://www.macmillandictionary.com/us/dictionary/american/assert: 
"to state firmly that something is true"


As a bonus, Googling "statement of fact" in case that isn't clear 
to you what that means (maybe that's what's throwing you for a 
loop? You seem to be equating statement of fact and facts so 
you've clearly got some understanding wrong for the definition of 
those two):
http://en.wikipedia.org/wiki/False_statements_of_fact

False statement of fact... You can't possibly suggest that there 
exists false facts, but false statements of facts do exist, 
proving that statement of fact != fact.
