Assuming some early primordial life did evolve on Mars, lets just says only algae and bacteria, would we be able to see that evidence today with just a camera on a rover?

Or would the evidence be destroyed by geological process/time?

People often rail against the idea of crewed missions to Mars and other bodies, but the fact is that a geologist or exobiologist could learn more in a day than the robot rovers, great as they are, could learn in months or years.

There’s no substitute for boots on the ground.

Earth has microorganisms deep in the crust that will outlive pretty much any worldwide disaster. I suspect that if mars had life at any point it will be found in the crust of Mars.
