The main discovery the mars exploration rover made was discovery of evidence of water on Martian surface.
On March 23, 2004, a news conference was held announcing "major discoveries" of evidence of past liquid water on the Martian surface.
A delegation of scientists showed pictures and data revealing a stratified pattern and cross bedding in the rocks of the outcrop inside a crater in Meridiani Planum, landing site of MER-B, Opportunity, suggesting that water once flowed in the region.
The irregular distribution of chlorine and bromine also suggests that the place was once the shoreline of a salty sea, now evaporated.
The NASA Mars Exploration Rover was developed in the early 2000s. The two rovers, Spirit and Opportunity, landed on Mars in January 2004.
The Mars rover Opportunity was launched on July 7, 2003 and landed on Mars on January 25, 2004 as part of NASA's Mars Exploration Rover mission.
it figured out if we could live on mars or if there was ever life on mars.
NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, in search of answers about the history of water on Mars. They landed on Mars January 3 and January 24 PST, 2004 (January 4 and January 25 UTC, 2004). The Mars Exploration Rover mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet.
The first rover to reach Mars was the Sojourner rover, part of the Mars Pathfinder mission, which landed on Mars on July 4, 1997. The Sojourner rover conducted scientific exploration on the Martian surface for about 83 sols (Martian days).
No they are different rovers.

The Mars Exploration Rovers (Spirit and Opportunity) and the Mars Science Laboratory rover (Curiosity) use the VxWorks operating system.
The Phoenix lander landed on Mars in May, 2008. It isn't really a rover. It is a lander, doesn't move around like the Mars Exploration Rovers - Spirit and Opportunity.
