I think, therefore I am.
The fact I can respond to your question is evidence of the physical properties of the universe itself. Everything else is an afterthought. Once you have come to this conclusion then you can begin mapping out your surroundings.
The moon and Venus become your closest companions. The two most visible beings in the sky who carry themselves besides the Sun itself which you have obviously known since you have lived your entire life dependent on it. If you look further then you will see other points of light that defy the other points of light. "Planetes" or wanderers in Greek.
And when you point this out this profound fact of nature then other people will dismiss you because the fermentation in their pottery is more important than the existence of Mars.
