With such a thin atmosphere, why would a light shining upwards be visible from the side? For a light to be visible laterally like this, you'd need atmosphere for a scattering effect and a very bright light. A light pointing upwards from the surface of Mars should only be visible to something looking downwards. Concluding that it's intelligent life "using lights as we do" is just a wild claim with no backing. From the evidence it's pretty obvious that it's a holographic projection sent backwards in time from humans in the future.
