My titled question was can a planet without moon/moons be habitable?

In more depth, how would that planet be affected overall; without the moon to affect the tides and without providing light during night.

How badly would oceans/seas be affected, could life be sustainable within them (fish, algae...etc.?

Lastly would the atmosphere be majorly affected, much stronger or weaker than would otherwise be possible on said planet?

And I already know that the heat reflected by the moon is to insignificant to truly affect the heating of the planet.

From a writer's perspective a planet like this is an interesting concept because to humans it would be a foreign idea, stars would be that much more visible at night as well as it would be very, very dark.
