Waves are generated by a number of things. One of them is the currents, where oceanic currents affect the movement of the water and this has a rippling effect. The closer the resultant ripples get to the coastline where the water is typically shallower, the larger the ripples and this is witnessed as waves.
Another generator of waves is tides. As the tides rise and fall, the body of water moves and creates ripples and waves.
Wind also creates waves. The movement of air disturbs the surface of water and this results in ripples. Accumulatively over many miles the magnitude of the waves gets larger, and again, where the water gets shallower near the coast, the waves gain amplitude (size).
Movements in the earth's crust under the sea also creates waves. This is what a tsunami is - large waves created by sudden movements in the earth's surface under the sea, typically by way of earthquakes. Other tremors, and underwater volcanoes also can have the same effect. Also, earthquakes with an epicenter on land but close to the sea can also result in large waves. A resultant collapse of land mass can create huge waves, such as that caused by the collapse of one side of Mt. St. Helena when it erupted.

Fill a drinking glass with water, then at an angle 0f about 35 degrees blow on it - you will observe that the surface of the water ripples. That is what the wind does to vast expanses of water called Oceans and seas. That is how waves are formed - the wind creates them.

Its the same reason we don't fall off the planet, the same reason there is wind in the sky, the same source of the movement from within the earth and inside your soul. It is the magical everlasting flow of energy that sustains life. Without the currents and waves many lifeforms would perish, its sacred and you are wise to ponder on such things, just remember the scientific answer isn't always the one you want!

there are many factors why sea creates wave, the wind, the movement of the earth to the sun, the gravitational pull of the moon, the heat and cold, the gravity of the earth, etc,...

Waves are almost wholly the result of the wind blowing across the surface of the water.

They are caused by the gravitational pull the moon causes on earth, and the strength or lack of ferocity of the wind determines the size and strength of them.

The moons gravitational pull has an effect. If the mood disappeared there would be chaos and loads of floods.

Because of the Moon

This is due to the Rotation of the earth around itself and rotation of moon around the earth.
