The moon does have a gravitational effect, like any body with mass. As the moon is much smaller than the earth, the gravitational force is much lower, however the moon is still pretty big!! Consequently it has a big effect on the water on the surface of the earth.
The sun also has an effect on the tides. when the sun and moon are in line they pull together and produce bigger tides. When they are out of line, the tides are smaller. BIg tides are called Spring tides, whereas small tidea are called Neap tides.
Have a look at www.swanturbines.co.uk for a great tidal power idea

The moon does have gravity. It's roughly one-sixth of the Earth's gravity, but that is still enough to create tides.

the moon does have gravity (about 1/6 of ours), and the reason its gravity (not really gravity) affects tides is the same reason the earth orbits the sun. Size.

The Moon has gravity at the surface. If it hadn't, it would have been impossible for anything to land there let alone have people walking there. The Moon does not have a magnetic field but gravity and the magnetic field are entirely different.

The moon has gravity. Anything that has mass has gravity, including the computer you're on, you just don't notice the gravity of your computer because it's not big enough to have a significant effect.

the moon has gravity, because it has mass. it's gravity at the surface is about 1/6 the gravity on earth. Thus an object on earth will weigh only 1/6 as much on the moon.

The moon does have gravity... just not that much. Also, it isnt the moons gravity that effects our tides, it is our own gravity pulling at the moon that creates our tide changes.

The *difference* in gravitational force from the Moon from one side of the Earth to the other is what makes the tides. That's a distance of 12000 km for the Earth, less than 2 meters for you. The amount of gravitational pull on you from the Moon is a millionth the Earth's gravitational pull on you. I worked it out once as 980 N on me from the Earth, 0.003 N from the Moon. Is it any wonder we don't see any effects? Unless you're looking for some sort of metaphysical nonsense, in which case you're in the wrong place... Edit: What, exactly, are you asking? You seem unsatisified with "yes, but the gravitational effect is insignificant". Whether you like it or not, any other supposed effect is not science: it is superstition.

it has gravity and the action of moons gravity causes the tides

The moons itself doesnt have gravity on the surface, therefore you can bounce. But the moon has a very strong gravitational pull which still affects our tides.
