Nope. You will observe the effects of gravity. You will not observe gravity itself. What if I go to the top of a 20 story building and drop a helium balloon? Would this also result in an observation of gravity? How come gravity affects people but not helium balloons?
You know, you can very easily put this debate to rest and prove everyone else wrong just by describing gravity. That you cannot can only be construed as a flaw in your position.
Nope. You will observe the effects of gravity.
Semantics. Gravity is a scientific fact. An undeniable fact by even the most obtuse. Evolution is not a fact and it has never been observed in any scientific manner. Evolution proposes the tranformation of species, such has never been observed. Gravity proposes the pulling of a smaller mass towards a greater mass, this is observed on a daily basis by every human being on earth. So there are scientific theories which are absolutely true and evolution is not one of them.
