And can anyone conceive of what it would be like without the moon in the night sky?

Dark.

If the moon was not our companion....life as we know it would likely not exist....

The earth's axis would wobble a great deal more than today....causing extreme climate changes...weather patterns, atmospheric winds and tides would also change dramatically

Some theorize the earth would be covered in ice if that were to be the case......a perpetual ice age.
