But I think just because YOU or anyone else is not there to witness anything doesn't mean nothing exists or happened.

Prove it. If you have no evidence saying that an event did happen, other than it was likely to happen, you aren't able to say for certain that it did.
If you were to put a bear and a fish (alaskan analogy) in a soundproof airtight box, you could not be sure of the outcome unless you opened the box. You could not absolutely be certain that when you open the box the fish would be eaten, or if the bear would have suffocated from carbon-dioxide poisoning, untill you saw what had happened inside.
??? My statement just says you can't rule out the possibility of something existing or not existing just because no one is there to WITNESS IT, if you can have some sort of other evidence that leads one to infer that SOMETHING could be there, then you can't rule out that possibility that something is there.
It's like you see a puddle of blood on the floor, but no one was there to witness how it got there. What I said before was basically saying, just because no one was there to witness how the blood got there, it doesn't mean that it just appeared there spontaneously, "something" happened, or something existed once before.
Also, I was never talking about certainty, you can't be certain of anything, even about our "laws".
And if you can't be certain, like you said, how can you be certain that "YOU or anyone else is not there to witness anything doesn't mean nothing exists or happened" is false and that if no one is there to witness something then nothing must have existed. Prove that. See I don't understand what you are trying to argue, and how it goes against what I was saying.

Okay so first of all, how do you know the tree fell down if no one is there to hear it make a sound? If you do know the tree fell down then it, then tell me how can it NOT make a sound? Is it possible for it to not make a sound if it fell?
ADDITION: And actually what you said:

But the fact is, is that you cannot be sure of anything untill you see some sort of evidence of it being there.
Much of what we believe is simply the most probable action for the path of an event to take.
Is exactly what I was saying in the previous post.
