Is the moon essential to any life on earth? 

In other words, would there be any implications on the formation of life without the moon?

The moon stabilizes Earth's orbit. Without the moon, Earth's axial tilt would change over time, with major effects on the climate. Life could still exist, but it would have to keep evolving to keep up with this climate change.
Also, intertidal marine ecosystems are adapted to tides. These communities would be quite different without tides.
