Question

If no living creature existed

If there was no consciousness anyware to be aware of it surroundings,
such as the universe

would it exist?

If nothing knew it was there would it exist?

The answer is yes

If a tree falls and no ones hears it, does it make a sound

The answer is yes

Just because you do not witness an event it does not cancel out the
event

So another question is if that is the case what things DO exist that we
do not know about, maybe we can not see them, hear them or touch them
but perhaps still they exist

I wonder what they are?
