Since neither rover has a microscope or state-of-the-art mass spectrometer (due to budget and mass constraint limitations), we're therefore going to have to wait until we can study Mars rocks in a lab on Earth to really answer these questions - unless Perseverance just stumbles across a stromatolite lol.
Fortunately, NASA's already set that plan in motion. The rocks that Perseverance is coring will be brought back to Earth by a series of robotic missions, they'll return to Earth in the early 2030s. They will be the most scientifically valuable materials in history! Only then will we be able to definitively answer - yes or no- whether the area Perseverance is exploring had alien life.

Mark my words. SpaceX will land a human on Mars before NASA gets anywhere CLOSE to doing a sample return.

How close do you realistically think SpaceX is to landing humans on Mars? They haven't even crashed on Mars yet. I bet we get the cores before humans get to Mars

What vehicle will nasa use? Sls? Ha!

Whatever one they want to. Nasa have been there many times. SpaceX should aim to get people on the moon before mars

Lol they will need a bigger launch vehicle and a sizable return vehicle. Masa has never landed a payload of that size. They have no vehicle brother

Whats the biggest payload SpaceX has landed on another planet? SpaceX hasn't even landed a gram on another rocky body

You clearly don't understand what the mars sample return mission is. You don't need sls. I don't think they have a launch vehicle chosen yet but I believe falcon9/heavy would work as would Vulcan.
The sample return mission isn't some huge vehicle carrying humans to grab samples and come back. So they don't need a big rocket like that. Perseverance is gathering the samples and leaving them on the surface. A future mission will include a small rover and two helicopters I believe (like ingenuity) to collect the samples. These samples will be delivered to MAV (mars ascent vehicle) which is basically a beefed up sounding rocket. This will then drop the samples off in an orbiter that will then make its way back to earth.
The MAV and the rovers and the copters and the orbiter are all in development right now as well. We should see the next launch for this mission in the 2027 time frame, wherever that launch window is. And then I believe there will be another in 2030 or so. Then the samples come back by 2031 or something like that. Hard to remember off the top of my head.
While this is a complex mission it isn't too herculean of a task to keep within a few years of the plan considering sample caching is already started and ingenuity specs barely need to be modified.
While I honestly have no doubt that nasa will be using spacex for carry astronauts to mars one day, I don't think that day will be before 2032. SpaceX is already behind on starship. Not by a whole lot but they are behind their ambitious goals. We probably won't see a first test flight until the start of next year. They'll have to refine their earth operations and their lunar operations over the next few years. I doubt they even make the 2025 human landing on the moon at their current rate of progress (although faster than anyone else could do).
Starship could make the sample return moot though. It's much more plausible that by 2030 starship can do an unmanned mars round trip. The scale of samples that could be brought back would dwarf MAV. But we shall see.

What the hell would they use to lift everything off the surface? They need several vehicles and haven’t even started development on any of it. Also funny that you mentioned two spacex vehicles hahaha. NASA is nothing but an astronomy club these days

Are you illiterate? I literally wrote out exactly what they would use. MAV. Mars ascent vehicle. It's a beefed up sounding rocket. They literally have started on these "vehicles". I work with people who currently are doing trajectory analysis for MAV. Of course I mentioned two spacex vehicles. They would be great for sending the orbiter and even the lander/MAV. Maybe learn what you're talking about before just saying shit? Especially since NASA is currently operating more vehicles on Mars than anyone else and has extensive knowledge on landing and orbiting it.
As for the astronomy jab, I repeat they have more vehicles operating on Mars than anyone else. They have satellites around Jupiter. They're about to send a flying laboratory to Titan. They operate the international space station. They do a bit more than astronomy you dolt.
