The word you may be looking for is "faith." Faith is a believing trust in something which cannot be seen, though you may see the effect of it. For example: no one can see gravity. We know it exists. We study it. We see the evidence of it, but gravity itself cannot be seen.
A Pegasus is a fictitious creature and has never been seen (if it even exists).
No a basilisk is a mythical creature, never been seen.
In many cases yes, it is having faith that something not seen exists. I have never been to America, but having been told by someone who lives there and having seen photos gives me the faith to know that America exists. I have not seen God, but through the promptings of the Spirit I have the faith to know that God does exist.
They were fascinated by it because that was new to them and never seen something that goes fast and can travel in less time.
This simply means that you have heard or seen something but you do as if you'av never seen.
Absolutely. Faith works like this........youve never seen the wind. you see limbs of trees move, objects change direction in it, you feel the air around you move..but youve never seen the actual wind itself yet you know it exists,right? ask yourself how and why you believe it exists. you'll come up with answers like i mentioned above. this is faith. spirituality exists in the hearts of those who believe in something generic and based on theory and research. faith exists only in the heart of a true believer.
no he is not. he has a girlfriend although he's never mentioned a name (but I've seen her so she exists)

That is typically referred to as an "invisible" entity or object. It is something that exists in reality but cannot be perceived by the human eye.
If its never been seen before then it doesn't have a neme yet but probably some new sea creature
belief, accepting something as truth without the burden of proof or evidence. I don't know China exists, I've never been there and seen it with my own eyes, I have no proof. But I believe the people who have, I accept their experience as truth.
