The even distribution of the spheres and being the same size just seem odd for a geologic explanation. There might be one, but I don’t have it. Mars has surprised me more than once. I am sure I will be surprised again.

The fact that they are all around the same size is really the kicker. Tektites would vary in size. So would sphere formed by other geological process. Why are these roughly all the same size? True, in some rocks, like granite, crystals will be of similar size because of the cooling rate and the amount of minerals in the solution, but it is nothing like this.

I just don’t know. I keep coming back to life. You can go to the beach and find seashells of the same species that are similar in size.

The problem I have with the spheres being formed from life, is that they are evenly distributed. Like with tektites, I would expect sphere, formed from life, would be in certain layers, unless they formed after the sediments were deposited. I would love to see a well cut cross section of the layers.

Could some ancient mars life have tunneled into the layers during the last time the area was flooded?

At this point, I am not ruling out anything. Mars has fooled me before. I’ll wait for more evidence.
