Lycopodias were used in the past for flash powder and sometimes for center 
pieces
on tables, are there any scientific or econimic uses in this present time or 
future time?


What makes scientists know that animals and plant life that were fossilized 
are millions and billions of years old.  Are there in any concrete evidence 
that says this is a million or billion years old.  Me and a couple of 
students were trying to figure this out.  

Another question is do we know for certain that the earth is over a million 
years old, or why couldn't it just be a couple  of hundred thousand years old?

Thank you for responding to who ever do!
