Are you sure it is not transparent in your cellar?

In the daytime space allows ''light'' to pass through itat night time space allows ''light'' to pass through it down your cellar with the ''lights ''off , space allows ''light'' to ? (I will let you finish the sentence).

clearly the egg came before the chicken... I believe it so it must be fact. Evidence? What is this evidence of which you speak? The truth should be immediately clear and obvious, as it is to me because my eyes have been classically trained in true vision. Thus if we really look hard at this proof so far, we can safely conclude this line of argumentation is bologna.QPQ (quid pro quo)or was it QED?

clear.jpg (8.36 kB . 985x507 - viewed 4359 times)The above diagram is an artists impression of a overhead view a 100ft deep swimming pool, the bottom of the pool is painted black and the water is crystal clear and been cleaned from any other particles. The artist impression was drawn in the daytime.
OK, now imagine I put a goldfish in the pool.It's daylight, so you can see the fish.Now wait till it is night time.The fish is still there- but you can't see it.The difference between the scenarios is that in one case it is light, and in the other case it is dark.If there was no such thing as dark, you would always be able to see the fish.But you can't see the fish at nightso some condition which leads to the invisibility of the fish must exist.We call that condition darkness.Why are you pretending that this is anything other than obviously true?

I have drawn the pool again in daylight , this time I have put a black fish in it. clear.jpg (8.36 kB . 985x507 - viewed 4217 times)
Just answer the question: why can I see the goldfish in the daytime, but not in the night?Here's a hint.At night, it is dark.
