And humans need not step foot on either planet to begin any viable process. Heat is a form of energy, which under certain frameworks can be used for chemical and bilogical processes one is looking to push forth. This cannot be the case (heat energy) on Mars.
Not quite sure what you mean here - there is not enough heat energy on Mars right now. But with sufficient amounts of carbon dioxide, and maybe some water vapor (and a lot of artificially created dust storms to act as a temporary catalyst), there could be enough heat energy retained on the surface to be usable for whatever means.
moon is too small to hold an atmoshpere. Mars is barely big enough which is proubly on of the reasons its already died. eventually earth will suffer a simlar fate when our atmosphere escapes (altough from what I read it will take about the same time for the sun to burn out so we will have bigger problems then)
Mars is 4,222 miles wide.
Saturn's moon Titan is 3200 miles wide, and it has an atmosphere thicker than Earth's, which also is rich in organic compounds.
What planet is currently conducting nuclear reactions? And chemistry doesn't deal in nuclear reactions (that's physics).
Jupiter, maybe. I remember reading somewhere that Jupiter emits more energy than it receives.
Link. Something's providing an internal heat source. Saturn also possesses this quality.
Ok, scratch that. Apparently it's not because of fusion or any nuclear reaction. It's just still cooling down from its formation.

We gonna need a whole ton of stuff for it though.
Yeah, we'll need to advance about 10,000 years in energy, material, flight, and engine technology.
Well, the original poster did allocate anywhere from 50,000 to 250,000 years for this project.
So heck with it, use all the planets and asteroids themselves to create a Dyson sphere. Though I'd think another star would be a better idea, like a newly formed white dwarf. Its smaller size would mean that a much smaller sphere could be built (fewer materials) and the star itself would last a lot longer. 10 billion years is the expected lifespan for a star like our sun (5 billion left for ours though) in its current state. White dwarf stars also have a lifespan of a few billion years, before they sizzle down to a brown dwarf. Benefits there - no red giant stage, which nicely wipes out the Dyson Sphere. And you're left with a damn big diamond to do with as you please.
