Newton's third law is a generalization. Newton's law of gravity is a particularization of it - it only refers to gravity. That's how it's taught in physics, too. Therefore both of them form a conclusion that the earth is round.
You are clearly horny. Horny people don't argue very well. Also, you must be horny for a reason. I believe that reason is because you like to think of yourself as a master debater. Read the definition of "evidence" again. Read what you just wrote. Read your comment that you don't think Newton's third law is not evidence for the shape of the Earth. Explain how what you've said, combined with the dictionary definition of "evidence" is not a contradiction.
Explain what? Are you dysfunctional beast? You need basic logic explained to you? Or are you just horny and trying to make it seem like other people have similar "problems" to yours? I'd go for the last choice, which I pity you for. Try and get some ass mate. If you can...
Since Newton's theory of gravitation is a particularization of his 3rd law, and since a direct result of gravitation is "the very existence of the Earth, the Sun, and other celestial bodies; without it, matter would not have coalesced into these (
ROUND!!!) bodies and life as we know it would not exist" - and we "know" life to be taking place on a round earth, at least on wikipedia, where this quote is taken from (ironically, under
http://en.wikipedia.org/wiki/Newton%27s_theory_of_gravitation), how can you not understand that:
- if we define A to be Newton's third law;
- "----------" B to be Newton's theory of gravitation;
- "----------" C to be the round earth
then clearly since B is a particular case of A, and B explains (or "accounts for", or whatever word you want to pick so we don't get stuck in form anymore - since that's all your mind has the power to perceive) C, then there is a connection between A and C THROUGH B, and therefore the two (A and C) are interconnected themselves. It's not rocket science.
