If you want to go further down this rabbit-hole, I recommend this video next… Proof Mars' deep-trench called the Vallis Marinaris was caused by a plasma-discharge/electrical-arc, not any kind of erosion of water-flow.
If you watched the first video, you will find this to be a satisfying supplement, which will make you more confident in digesting what you just saw. Enjoy…
