Because nothing has ever been to a comparitively earthlike planet, here is a comparison that adds life to compare and some metal to salts existence.

Inside the head of the person seeking funding for a quantum computer is a model of that computer.
Does that count as a simulation?
It's an interesting idea, but tides rise and fall due to the rotation of the Earth. A sustained tide for several days would only be possible if the Earth were tidally locked with the object (which wouldn't happen for a temporary system).
It also wouldn't explain "raining for 40 days and 40 nights"
There are many biblical and pre-biblical accounts of a global flood, so there may be some actual events that inspired the stories. One of the theories has to do with filling of the Black Sea: https://en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis
My goal is to one day own and live in a windmill, how efficient would the sails be at generating electricity? or would it just be better (or possible) to fit a modern turbine to the windmill?
Ultimately, virtually all gas in our atmosphere will eventually be lost to space. There is a distribution of particle velocities in a gas, with most of them falling around some mean value. There is also a percentage of outlier molecules that move much more quickly than the mean value. Some of those molecules will be moving faster than the Earth's escape velocity. Those molecules will, of course, be capable of escaping the Earth's gravitational pull. This is one fact that drives atmospheric loss over time.Goes in my mind I have never heard of rain being considered linked to meteorite activity by methane ignition neither forecast mm or inches from upward lightning.
Lighter molecules have a higher average velocity than heavier molecules, and are lost more easily as a result. This is one reason the Earth does not have a significant amount of hydrogen or helium in its atmosphere. Jupiter, with its much stronger gravitational field, can hold on to those light gases much more effectively. Its lower temperature also helps with this (cold gases have lower molecular velocities than hot ones).
Another factor causing atmospheric loss is solar wind. The Earth's magnetic field deflects much of it, and as such has retained a thick atmosphere over time. Compare this to Mars, which has a weak magnetic field and thus has suffered much more severe atmosphere loss. Its lower gravity may have contributed to this as well.
Methane, being lighter than oxygen or nitrogen, would indeed be lost more quickly. It is also important to keep in mind that methane reacts with oxygen to form carbon dioxide and water vapor. This would also contribute significantly to decreasing the methane content of the atmosphere over time. Methane is also being continually produced by biological processes.
