Skin Tones based on latitude on the Earth are a lie....

around Jerusalem is the 33' latitude mark.  However, when a person goes north when looking at the skin tones of people that lived around Jerusalem the people do in fact have lighter skin tones.  When a person goes south towards the "crux" constellation at the south pole the skin tones do get darker. 

But there is a problem.  When a person comes to America, the people at 33' latitude who were here indigenous are dark or darker than the people that lived around Jerusalem indigenous if they lived in the north.

The girl in this photo appears as if she could have lived around Jerusalem or is indigenous to the area....but this is actually a photo of a Navajo girl.

The reason that the people indigenous to America have darker skin tone north of 33' latitude may actually be due to lifestyle of the ancient people but also a "gift" from the creator.  They were astronomy people and were often outside calculating the times and seasons.  They believe in supernatural things, so they did not believe in institutionalized anything......thus the need to be "indoors" and constantly do paperwork, even in the middle of winter.  In the middle of winter, it would be common to find a fireplace outdoors and enjoy the presence of the fresh cool winter air.

Perhaps this connection to "nature" by the indigenous people has some connection to the origin of their ancestry (which was from Creator God after Noah's Ark......not from Darwinist evolution theory).   Genesis 1:14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:

A common way to identify time among indigenous people was by the "moon"  "falling leaves moon" has significant value in the recording of time.  They also calculate the movement of the planets through the constellations as well.

So should Christians continue to keep the Gregorian calendar, simply because it is "superior" to all the other calendar's on earth and has been used for over 400 years?  The answer is this, keep up with the CREATOR'S calendar first, and then consider what is necessary to get business done(the Gregorian calendar is only business calendar not a truth calendar) in this world.

The more adequate a person is in identifying the location of the planets, the phases of the moon and the location of the sun, the better a person will be in identifying with the true CREATOR'S CALENDAR.  You won't be able to identify when Jesus would "return" so to speak, but you will identify with the truths of the scripture by knowing it.

A lot of people may call you "nuts" or "insane" for keeping up with so much astronomy, but they are not the creator.
