What do we not understand about our eyes? Light enters through our lens and hits rods and cones in the back of our eye stimulating nerves to send electrical signals to our brain.
The brain we do not fully understand... no offense but you sound like a crackpot
Blind people can perceive the universe, i understand what you are saying though. Without our senses, touch/smell/sight/hearing we distinguish anything around us, it would be like living in a void. Who knows what is like to lose all those senses. Despite this, the world will still exist. If our thoughts were so powerfull we could create anything from nothing.
Your bold points seem a little crazy.
It is not very clear to me, are you trying to say that the universe is created because we as humans can perceive it?
