Juvenile water.
When a volcano erupts, 20% of the material spewed from it is water. This water is called Juvenile water. This water has come from very deep within the earth, and is held under very high pressure. When the eruption occurs, this water is spewed high into our atmosphere, then comes back down in the form of rain. This water is said to have never been on the surface of the earth. After observing the current eruptions rates, about 20 per year, scientists have determined that these eruptions release 1 cubic mile of water onto the surface of the earth every year.
If you were to take and measure all the oceans and streams to see how many cubic miles it would take to fill them. You would come to a number of about 340,000,000 cubic miles. If you take 1 cubic mile per year and divide it into 340,000,000 cubic miles total. You'd get 340 million years for our oceans, rivers streams lakes etc.... To be filled. But science claims the earth is 4.3 billion years old. Where's all that water? So just 340 million years ago, there was no water on the surface of the earth. And if there was water, then these volcanic erutptions just added to it. 340 million years is not even half, or even 1/4 of the 4.3 billion years that science claims the age of the earth is. Does this fit within the evolution time line? Nope, 340 million years ago puts us right in the middle of where we had fishes evolving. Sounds like a fish out of water problem to me.
So problems we can see involving volcanoes, and the claimed age of the earth is:
1) Where is all the volcanic ash from all the eruptions it would take to form our atmosphere?
2) Where is all the lava formation we should see to go along with all the eruptions?
3) Where's the 4.3 billion cubic miles of Juvenile water that is spewed into our atmosphere over a 4.3 billion year past?
4) With all the volcanic ash, and black smokers. How did our oceans become clean?
5) With 4.3 billion years of volcanic eruptions, how did our atmosphere become clean and clear?
