Our big moon had a lot to do with our evolution, probably sped up the transition from sea life to land life by tens of millions of years. There are a lot of earth-like planets out there, but how many with oceans and big moons in the Goldilocks Zone? Maybe we're the elder race of this galaxy, thanks to our strong tides. I think an aquatic technological species would be handicapped in developing electronics and space travel.
