Diverse minerals found in Mars

Curiosity rover, the NASA’s rover on Mars, has found a variety of minerals on the red planet. These layers of rocks are predicted to have been deposited about 3.5 billion years ago, coinciding with a time on Earth when life was beginning to take hold. In fact, early Mars could have been very similar to early Earth.

Four samples were drilled near the base of Mount Sharp:

Telegraph Peak sample had minerals similar to quartz.

Buckskin sample had tridymite, which is rather strange considering that the mineral is found from partial melting of a planet’s crust (such as Earth’s crust), and Mars is assumed to never have had tectonic plates

Confidence Hills and Mojave 2 sample had clay minerals, generally formed in the presence of liquid water with a near-neutral pH.

There were several other minerals found. So, since Mars had a habitable environment in the starting, could it be that there was life on Mars and was later wiped out? or rather life managed to reach Earth from Mars?
