    Imagine the energy necessary to move it closer to Mars to have it dropped on the surface!

    That's not a huge problem - you just need to drop the perihelion close enough to let Mars pull it in. It's still a lot of energy, but there's no reason to go brute force about it. Letting it happen over a few thousand revolutions (say, 10,000 years) wouldn't change the rest of the timings much. You could do things faster, but that would need more energy.

    And who knows what remains of Mars after the impact of 9*10^18 kg of stuff.

    Impactor that size - that's in the right order to make some structure the size of the present North Polar Basin - a bit less than a hemisphere, some kilometres deep. Big, but far from planet-busting.

    How much of the atmosphere gets blown off in the impact is hard to estimate - which is going to be one of the reasons that adding volatiles for an atmosphere is going to take millennia or longer - like doing a thick weld, you have to let the work piece anneal at some points in the programme of work.

    Maybe move Venus to the Mars orbit and create a bi-planetary system like Terra/Luna.

    Crossing orbits in a planetary system? That's not likely to end well, and is likely to take a long time - a few hundred thousand cycles or around a quarter million years. It'd be far safer to move the Earth out to co-orbit with Mars (while simultaneously stripping the top couple of km of the surface, oceans soils, ecologies, and putting it all into cold storage in space somewhere) while moving Venus out to take Earth's place. Then re-surface and re-atmosphere Venus while the orbits stabiise (another few hundred thousand cycles?) and take the Earth's ecosystems etc out of cold storage, put everything back in place et voilà - more living space.

    With a bit of luck, you might get the job doe in less than a million years. Quite how many species of humanoids will be around to see the end of the project is your guess.

    Naked women as porn don't appear in primitive art

    Naked women as pornography couldn't appear before the widespread adoption of clothing. And if you can remember wanking over your Dad's collection of National Geographic with the bare-titted "ethnic" photographs, you'll realise that what is considered pornographic (or stimulating) is culturally variable.

    the agricultural revolution, when people started living in fixed homes and had leisure time while well fed.

    The evidence is pretty clear that the adoption of agriculture resulted in less leisure time, more stress (from having land, crops, seed stocks and stored grain to defend against both rats and thieves), worse nutrition (including deficiency diseases, due to a less varied diet), and diet-related diseases such as diabetes. About the only thing that improved was the overall calorie count.

    Prior to that, leisure time implied seasonal shortages without enough available food to make hunting and gathering worthwhile.

    Seasonal shortages were why nomadic people moved somewhere else. Once you've got crops in the ground, then you've literally bet the farm on making a success of the agriculture. And you're vulnerable to the local strongman coming along and demanding "protection" for his "defence force" of "soldiers".

    and breasts containing sufficient milk to feed a child.

    You don't seem to understand how the mammalian breast works. The milk gland comprises about an A-cup (does America use the same bra-sizing system as Europe and Africa?) ; the rest is useless fat. Or, if you're a porn star, useless silicone plastic.

    Also, starting at that time men appear to have spent a few thousand years making dick pics before they even started on pictures of sex.

    Hmmm. Colour me unconvinced. I can think of a number of phallic standing stones and a few carvings in the published record, but for the vast majority of megalithic constructions I've seen (hundreds, over the years ; they're pretty common here - I bumped into one just last Sunday which I completely wasn't expecting) look about as phallic as something that doesn't look very phallic. That's dating back to well into the "Bronze Age", if not into the "Copper Age" (which are diachronous units in any case).

    It's in Britain. which means it could be either in Scotland, or in England and Wales, or Northern Ireland.

    If it were in Scotland, the government of Scotland has stopped fracking (actually, it's just declined planning permission for any fracking operations - legislatively easier and quicker). Scotland does have a "right to roam" which which does allow most land to be accessed by most people, as long as the visitor's behaviour is reasonable (eg, not burglarising properties, damaging fences, crops or gates). But that's irrelevant. Otherwise, the decisions are taken by the London government. Most of the land in England, Wales and Northern Ireland is not in public ownership, and even if it is, there is not a general assumption of any right of public access except on specific defined routes called "rights of way".

    Basically, your assumption of US legal concepts applying doesn't work, because it's not America. Neither of the legal systems possibly involved follows from American precedents.

  17. Forcing 85% of the world population to change clocks for no apparent reason, to appease the 15% that live where this matters

    Living in Scotland, and having lived almost on the Arctic Circle and on both sides of the Equator, I'm perfectly happy dealing with DST. A 1 hour change every 6 months is pretty trivial compared to a 6, 8 or 12 hour time shift every week or two, which is what you get if you're working in 24x7 operations.

    I honestly don't know how many equatorial to tropical to temperate countries (ones below 45 degrees of latitude, or whatever number you choose) just don't bother with a DST, But I bet quite a number don't. If that number includes even one of India, China, the Philippines or Brazil, then your 85% dog being wagged by a 15% tail becomes pretty dubious.

  19. 1-Ceres isn't physically large enough to have more water than Earth. If it were 100% liquid water, it still would amount to less than half the amount of water on Earth

    Let's check that - mass of Ceres is approximately 0.0009393 * 10^24kg, while Earth is 5.97 * 10^24kg, for a ratio of 0.00016 (0.016%). My collection of bits of solar system data gives the proportion of water (by mass) in Earth as 0.00022. that would be about 1.4 Ceres masses. Not a wild disagreement, since we've considerable uncertainty about the water content of the Mantle (80-odd % of the mass of the Earth).

    Actually that would mean the Ceres would contain enough mass of oxygen to give Mars a workable atmosphere, if it were all water. but if it were a few percent water, then it's a lot closer a question.
