I already have a feeling there is crude beneath mars. Finding evidence of life can prove this. There are also rare earth minerals, especially gold. The way we get it is by drilling and then pump it to container ships in space. The ships never enter either atmosphere instead they dock at pumps that take the oil to and from the surface.

Oil and gold are all that matter. On this planet anyway. From what I have learned, gold is in all places , a result of the big bang. Oil, on the other hand takes a right condition, and death of a lot of organisms to produce something useful. Is this post a troll?

robots... they are doing it here on earth. and an oil rig is not that difficult to blast into space, especially if its in pieces. And getting there and back is just a madder of gaining volocity and then floating the rest of the way, remember the ships never land they stay in space.

I think it would be cheaper to develop getter ways of getting energy from the sun and wind than hauling oil from mars. Can't people break free from the conditioning we have been taught for our need of oil and gas If we are going to fix this problem the last thing we need to do is build more rockets.

Sadly, if Mars was made of nothing but oil & gold, it still would not be economical to get it and bring it back.
Here's what I mean:
Let's suppose the oil is not on Mars, but much closer - orbiting the Earth just a few hundred kilometers up
(orbital speed at that altitude is ~27,500 kph, so no, you cannot use balloons to reach orbit).
No need to drill - let's just imagine that it is just orbiting up there, waiting for us to come and get it. All we have to do is launch an empty oil barrel, fill it up, bring it down to Earth to sell.
An empty oil barrel masses ~20 kilograms.
The cost of launching 1 kilogram to orbit is ~$20,000.
Thus it would cost ~$400,000 to launch that empty oil barrel into space.
If we then fill it up and bring it back to Earth, we can then sell that barrel of oil for the current market value, which is ~$100.
$400,000 spent for a $100 return.
So you see, the problem with all schemes for mining space (whether its the Moon or mars or asteroids, or maybe just manufacturing things in free-fall) is that the cost of getting the equipment up there is way too high. In the above example, even if we could reduce the launch cost by a factor of 1,000 it still would be too expensive to make the effort pay.
Don't get me wrong - I want space colonies. I want orbital factories. I want to have my 100th birthday party on the Moon (you're invited, Raj) - But the high cost of payload-to-orbit is a huge problem. There are good proposals out there for systems that would be very cheap to operate compared to present-day rocket technology (Maglifter, StarTram, Skyhooks and Space Elevators), but the front-end cost (what it takes to build & setup these things) would be in the hundreds of billions of dollars, and would take 10+ years to develop. It takes resources, foresight and determination to invest in the future like this, and the financial rewards would literally be beyond imagination.
Sadly, neither the governments nor the corporate consortia that have the resources possess the foresight & determination to make this bright future a reality. I don't know how to wake them up. Ironically, shouting something like, "Oil & gold on Mars!" is the sort of thing to do it - but we need something that is real and attainable - not just motivational.

...or actually having life.

Funny post, this is how Mars/Moon harvesting/drilling/refining will work;
Drill on Mars/The Moon, that which is found on Mars/The Moon will be used there. Factories will be built on Mars/The Moon, want to make some rocket fuel? The rocket fuel factory will be built on Mars/The Moon, that's the only feasible way it will happen. So don't expect any transportation from one body to another in any great quantity to ever take place it would not be economically worthwhile.
We as a people, species, need to build bases/factories on The Moon & Mars, only men with vision have had this foresight, namely J.F.K. & George W. Bush. Can you name another president that had this in mind? Add them to the list. I simply look forward to the future of The Moon & Mars, when politics is set on the side and the future of humanity is pushed to the limits beyond our blue marble.
There are also rare earth minerals
