Here is a video which took me less than half a minute to search for and find on Youtube which quite adequately both demonstrates and explains how not
only planet Earth was formed, but indeed also where all the "wet stuff" came from.
National Geographic: The Story of Earth
But, if you happen to be unable to watch the video at the moment and/or would rather read how it happened; I will supply you with a simplified version
of the scientific explanation.
Before the solar system had formed into its current state there were no planets and no moons, only the sun and a giant cloud of dust containing the
different elements of the periodical table which was the result of the supernova which gave birth to our current sun.
While this "dust cloud" orbited the sun, the dust stuck together and formed small rocks, which collided with each other and formed bigger rocks, which
in turn collided with one another and formed even bigger rocks (also known as asteroids) and they in turn collided and began to form small planets
which as a result of their mass and gravity got bombarded by "space-rocks". Ultimately, over the course of a very long time, most of the dust cloud
had accumulated into the celestial bodies that we have in our solar system today and thus the Earth was born.
However, the Earth was basically a giant ball of lava as it had not yet cooled but as time progressed and it slowly but certainly got cooler and
cooler, the ice that were contained in the asteroids (because it is quite cold out there in space) that still were bombarding the planet constantly
finally didn't instantly melt into water and vaporize, as the temperature got closer and closer to where water can exist in a liquid state.
As puddles grew and turned into lakes, and the lakes grew and turned into oceans, so did the water vapor rise and create clouds which again cooled the
vapor and poured the water back unto the surface of the Earth (this phenomena is called "rain"). Which means that whatever water arrived, no water
ever escaped and thus over the course of millions and millions of years the wet, pale blue dot that we exist on today was what it is now, as the
volume of water on the planet kept increasing.
And that is where (at least most of) the "wet stuff" came from.
Oh, I might I add that you really should research why a global flood would have been impossible as described in the Bible. It might do you well to
understand why this would be that case, considering that if it actually had happened, you and no other complex life-form would still be here.
