Paul, 
Strike two: you totally missed the point again ! I never contested the 
possibilities that an observer on Mars (or any other planets) could observe the 
Sunrise and Sunset. My point is that only the Earth has physical life and 
physical intelligent beings living on it. And this is a good physical reason to 
give a bias to the Earth based observer. If you don't agree with this, it is 
because you are blinded to the core ! 
Marc V.
Well I'm up for three! Perhaps you have trouble with 'physical'? Your use of 
physical -- as picked out in gray above -- is essentially redundant ie not 
needed, irrelevant and possibly misleading. Where I have picked it out in 
olive, it is simply incorrect. A physical reason is one based on physics, or at 
least something objectively demonstratable. Examples - "It is physically 
desirable to use a truck of two tonne capacity to transport this large boulder 
-- the boot (trunk?) of your compact is just not equal to the task!"; "It is 
physically impossible to hold one gallon (imperial or US) of water in this two 
litre flask"; "You may try to outrun a bullet from my gun sir, but you will 
find that it is physically impossible"; etc.
My original statement was "...they cannot all be correct and there is no 
physical reason which gives a bias to the Earth based observer..." with which 
you have dissagreed. What I intended that you should understand from this, is 
that if I place a group of intelligent but largely ignorant beings on the 
Earth, another on the Moon, and a third on Mars, then, on their observations, 
they would likely all come to the same conclusion ie that they were on a 
stationary body, that they were at the centre of the universe, and that it 
would remain that way until they became scientifically literate and 
knowledgeable.
What each of these groups would discover is that in all cases, the Sun rises 
over the eastern horizon and sets over the western horizon but that on Earth 
this occurs at a frequency of once per 24 hours, on the Moon 29.53 Earth days, 
while on Mars the frequency is 24h 39m 35s(Earth). They would each note that 
the stars rise over the eastern horizon and set over the western horizon but 
that on Earth this occurs at a frequency of once per 23h 56m 4s, on the moon 
27.322 Earth days, and on Mars the frequency is once per 24h 37m 22s (Earth). 
These are among the physical reasons why they cannot all be right and there is 
no physical reason why the Earth observations should be set above the 
extra-terrestrial observations. To discover which -- if any -- of these is 
correct requires many more data.
