comment Is there any point on earth where the moon stays below the horizon for an extended period of time?
You can find a moonrise/moonset calendar for the South Pole here: timeanddate.com/moon/antarctica/south-pole. You can see that the moon never stays down for more than a couple of weeks.

comment Does science need support from religion or philosophy to explain the creation?
We use science to analyze questions that philosophy and religion can't answer. Not the other way around. If religion could explain what happened before the Big Bang, it would have done so 6,000 years ago.

comment What’s the object between the earth and the sun currently showing in Google maps?
It is. Most of the sun's size in this picture is just glare.

comment A curious relationship between lunar periods and the solar year
It took a while to sink in but this makes much more sense now that I know I should be comparing it to the sidereal year. Thanks.

comment Why are distant galaxies not visible in the observable Universe?
@EduardoSerra As for the no-center aspect, I've found the "problem" of locating the center of the surface of the Earth to be a good analogy. Back when people still thought the Earth was a flat circle, people would draw maps as circular area of explored territory with their capital city at the center of the circle. As more and more cities started producing maps with their city at the center, people began to wonder which city is actually the World Center. Then the Greeks realized that Earth is spherical and so it has no center; only maps have centers, and map-centers are arbitrary anyway.

comment Why is liquid water considered a requirement for life?
There are probably two separate questions to be answered here. 1) The requirement of liquid water for the genesis of life on a planet, and 2) how necessary a supply of liquid water is to the maintenance of life once it gets going.
