A question regarding the "illusion"

I guess most of us would assume we are human beings. We are separated from each other. We live on earth, which is a planet in the solar system, of a presumably infinite and mystical universe. The earth has physical laws, like gravity, and whatever else there is. We also have our beliefs, our thoughts, our self-image - produced by a "something", our brain perhaps. Our lives play out in a linear time, and our world has a history. We are born from our parents, who again are born from their parents, etc.

Now, hypothetically, lets imagine that nothing that you believe is exists, exists, except the illusion of it. What is the illusion you might ask? Ill get to that.

To put it in a different perspective: If you look around you. What do you see? Objects perhaps. What can you say about them? You can see them. You can feel them if you touch them. And maybe you can even smell or taste them. Now think for a second. What else, other than what you see, can you say you know that exists? But there is the world outside my window... isnt it?

But what defies existing? If, we say, that what defies existing, is what you know to exist - ie, what you can see. That is essentially all that would exist for a person who could have no beliefs and no assumptions.

So if you take away your beliefs and assumptions, all that would exist to you, is what you see. Taste would only exist as taste, but taste itself couldnt tell you that something tastes. There would simply be just taste. But then you would also realize, that sight wouldnt exist as sight, as in something sees (the eye for example) it would exist as object(s?) that are being perceived. Since there could be no sight. The assumption that it is your eyes that see, would also be part of the illusion. Now, if we take away the theory of seeing, then how can we perceive if nothing sees? A new realization would arise - you simply are it. What other options are there? There is no perceiving, there is only being. You are what you "see".

You also have your thoughts, they are there, because you think them.

So what would the illusion be? The illusion is what you believe and assume exists, outside of what is being perceived. If you have no assumptions or beliefs, there would never be a world outside of what is being perceived.

Now, thats the illusion. But this illusion has to arise from somewhere, right? What creates what you are? But mustnt that be you, too? Who else?

So... here comes the million dollar question (my question). If you perceive all that you are in manifest form, how could other beings exist, other than what you are perceiving (being)? If other people than you exist, how come you do not perceive what they perceive? How come you do not think what they think? Are you separated from yourself in other humans and animals, or do they really not exist at all, other than in the mysterious form of You?

... are "others" also just an illusion? Are you truely just alone, in your own complex illusion, essentially manufacturing your own beliefs and assumptions, composed as your mind, to make your own self-image believe that the world is real? You are WHACK! That is what you are, arent you?

Thoughts?
