The first life was indeed single celled animals somewhat similar to bacteria. However the environment was very different to Earth today and they may have lived near volcanic vents. It is very hard for scientists to tell because they left few traces, but modern day cyanobactyeria, blue-green algae and stromatolites (rather weird living stones – I have seen them in Western Autralia) may be similar tio early life on Earth.

@gannaz: I don’t mind getting my geek on and telling you one of my most excited times on holiday was visiting the stromatolites near Shark Bay in WA.
