“"This may confirm the ideas that Mars has an active weather system and that the atmosphere may be denser than scientists speculate."
No, they do not "speculate" - there have been half a dozen landers/rovers now that have measured the atmosphere. They know what the atmospheric pressure, wind speed and such are - they are not "speculating".
"After all, humans have a 26-hour biorhythm cycle, which exactly matches the length of a day on Mars! "
No, it doesn't. A day on Mars is just a touch over 24 1/2 hours.
Mars is interesting enough on its own without wild speculation and outright inaccuracies thrown in.”
