is the moon totally responsible for tides..if there is no moon ..will it mean no humans?

Answer 1

Assuming that the theory of evolution is right in this universe, yes.
The moon is responsible for earth tilted axis, tides, etc. As earth biosphere is a very complex system with process feedbacking process. One small disturbance will accumulate and result in great change after a long time, so if one of the microbe that don't suppose to dead 3 billions years ago died, the shape of human and animals may be different. That is a small disturbance.
A big disturbance like the loss of moon, will affect our biosphere greatly, I dont believe if there will be no human though, just the shape may be different.

Answer 2

The moon is mainly responsible for Earth's ocean tides, but the sun also makes a significant contribution to them.

Most astronomers believe that the moon was formed from debris thrown out when a Mars-sized object slammed into Earth not long after it formed. If that impact had not happened Earth probably wouldn't be tilted about 23-degrees on its axis and so there would be no seasons.

If we for some reason lost the moon today, Earth's orbit around the sun would be affected to some extent.

Answer 3

The moon adds a lot of stability to Earth's tilted axis. Without it, the theory is that the planet would "wobble" resulting in anything from no seasons at all, to one polar region getting nearly constant sunlight and the other being in constant darkness.

Answer 4

the sun is responsible for about one third of the magnitude of the tides. when the moon and sun are in phase (full moon and new moon), tides are particularly strong. when they're out of phase (waxing or waning quarter moon), tides are weaker.
