Not exactly, if we were too far there wouldn't be enough heat to sustain life in the first place, leaving no environment to evolve and adapt to
No, you really are missing the point. The bounds you are putting on life are that it has to be like ours. Life is anything that is moving on its own, if our Earth was very far away from the sun, then we would evolve into very polar creatures -- perhaps not needing heat or sunlight. Life as we know it started from amino acids and into bacteria...bacteria is some of the most resiliant life in this universe, able to adapt and conform to almost any condition within minutes (just because it has a rapid mutation rate)...so the underlying point is that we may have walked on five legs and eaten stones or something if the earth was very far away.
