Yes. Even if the question was ... If you think you see something, ... or anything of that sort ... then referring to the Marion Websters dictionary ... (EXIST)
1 a : to have real being whether material or spiritual
If the question was, "If you see something, does that mean it 'really' exists?" Then referring to the Marion Websters dictionary ... (REAL)
2 a : not artificial, fraudulent, or illusory,
the answer would be NO. If it were an illusion, or product of your state of mind, that makes it illusory. Existing, and really existing, are two subtly, different things.
As the question stands, the answer is YES. However, I would recommend improving the question, as someone might come along and delete this because of their own opinion - without looking up (or knowing) what the words actually mean. We cannot read into the question or guess at what you are asking. We have to take the question in its broadest, most literal meaning.
To be able to see through something means being able to see what is on the other side or inside of it. It can also refer to being able to perceive the truth or hidden elements behind a situation or a person's actions.
It depends on from where or when you mean. You cannot see the flag from Earth. You can see it in pictures from the mission. You cannot see it with a telescope. It also may not even exist anymore, having probably decayed after 40 years in direct, unfiltered sunlight.

It means that it isn't a bed bug is is something else. Like something that just apparently got in a form of way by either flying or walking.
Just because you cannot see something doesn't mean it's not there. The moon just isn't as visible during the day because the sun is so bright.
something that isn't there unreal; does not exist=•=
1. Greeks said that the fates were trying to tell you something 2. Your going totally insane

Yes, it's POSSIBLE. But the hypothesis is, almost by definition, meaningless. Basically the question is, "Might something exist that we can never possibly know if it exists?" I mean, what is the difference something that we can never know about its existence and something that doesn't actually exist?
Word "wereify" does not exist. If you mean "verify" then that is to confirm or to check that it is something is correct.

Ephemereal is something that exists yet does not exist aka an ideal
To envision something is to see it in your mind.
It can mean that you have a headache or something
Existence means that something is, such as you know you exist because, you see, feel, breathe, and interact with others that exist. People whom profess agnosticism, also exist. Therefore, agnosticism exist.
