(Areong, NASA). Kasei Valles, seen in MOLA elevation data. Flow was from bottom left to right.

Hmmm ... looks like running water on the surface, not a global flood. Please try again.

In the days when few travelled the world and saw clear evidence, this was never questioned. Now we know better! #isgenesishistroy. Daily lectures of real world science.

Do you understand what the word ‘Global’ means?

Global flood on Mars? Try again.

Oh, and another easily refuted detail - the article doubles the length of the outflow - it is under 1,800 kilometers.

There are signs of erosion during a wet period early in the geological history of Mars. There is no evidence of a single global flood there just as there is no sign of such a flood here on earth.

Many people have called in question the Genesis account of a Global Flood with a primary argument being there isn't enough water to flood the entire earth.

In 2014 scientists discovered a very interesting find. The lead scientist noted there is a vast reservoir of water under the earth's surface.

The money quote from the article.

"If [the stored water] wasn't there, it would be on the surface of the Earth, and mountaintops would be the only land poking out," he said.

Genesis 1:2 and IIPeter 3:5 says there was a global flood right here on the earth. This was long before Noah's flood. Jeremiah 4:22 - has an interesting instruction about a land before flesh man's time.

There are other explanations that require no water.

The Mississippi delta looks just like that. Doesn’t seem to indicate a global flood.

All - let me introduce you to a new book, ‘The Worldwide Flood: Uncovering and Correcting the Most Profound Error in the History of Science.’ It was published recently and is available at any on-line outlet such as this:

Why yes there have been floods on Earth equal or greater than the Martian flood
