The whole universe exists because you believe it does

At a quantum level the consciousness of the experimenters always affects the outcome of experiments which is where I begin: "The whole universe exists because you believe it does".

Would the universe exist if you didn't believe it exists?

If you didn't believe the universe exists then likely you wouldn't be alive very long at all.

Because if you are not living in the universe in a galaxy on a planet Called Earth where are you?

If you are nowhere then you don't exist and you are gone.

It's sort of like your hands: If you believe you have hands then you can do things with these hands like build a house or do a painting or hug someone you love.

But, if you don't believe you have hands (even if you do) then you cannot feed yourself and if you are alone you will soon die.

So, however you want to see this if you don't believe the universe exists then neither do you.

This is only logical.
