Well, there could be two sunrises and sunsets in a day, if you lived on the horizon, or treminator of day and night. (such a scenerio has been mentioned in south american legends as i have heard).
Also one side of the earth would exsperince a ice age, and one side a heat wave, or very tropical enviorment, as the water of the oceans would evaporate causing a humid mist to cover the side facing the sun, filght would be easier you probally could get a hang glider and float half way around the world on thermals. much simualr to some speculation about the life of people in south americas past, hang gliding from tall mountains, and people living in on tall mountains. mainly because the mist lower is so dense that you could not see through it, but you could walk down through the mist almost to the bottom of the oceans, like the atlantic, Islands that are now in the ocean such as japan and england would become large mountains and be connected to the main lands. (which may be the reason for some of the sturctures found of the coast of the islands of japan). Flying in a hydrogen ballon would be easy but it would be just as easy to fly using a oxygen ballon. another reason for living on top of high mountains the ablity to breath.
The earth does not spin very fast only about 1046 miles per hour, and yes it is noted as slowing down, but there are other effects that may cause the earth to stop, the earth tilts 1 to 1.4 degrees every 100 years of about 0.5 miles per year at this rate the north pole or south pole was facing the sun some time in the past 5,000 to 10,000 years ago. the sphinks and pyamids of eygpt are thought to have been built 3,000 to 5,000 years ago some say 10,000 years ago, for the earth to do a 180 degree turn it would take from 18,000 years to 12,857 years.
If we chose a date 5,000 years ago about the time of the sphinks and pryamids then the earth has turned 50 degrees to to 70 degrees, if you and the current axis tilt to that say 23.5 degrees, it for the most part defines that the entrance into the pyramids was faceing the sun when they where built, which makes a lot of sense.
If the earth stopped spinning it would start again, as the force that causes the earth to spin is the sun, so if you look at how the Planet Neptune spins, you would find the way the earth would start spinning again, the spin axis would be at what we call the equator.
The current equator acts in opposstion to the force that caused the orginal spina of the earth, and so the earth should stop spinning soon, haveing about 23.5 degrees left before it stops which comes out to about 2,350 years from now. even so the current postion of the earths rotation actually defines that the earth does not rotate on its oringal axis but on the second axis which is bascially just a wobble, kind of like a lot of skips around in a circle, some skips are 30 minutes long some 90 minutes ect..... one thing about being in this postion is that we could lose skips rather quickly in the wrong motion causing the earth to come to a stop much quicker, a very good reason for not allowing nuclear testing.
The ozone whole has marked features of this type of effect on earth, as well Elnino, however elnino remains difficult to sort out as the region was subject to nuclear testing.
Many of the facts of geology support that the earth had a different oreintaion and rotation, even the dipcitions drawn and made by eygptian and ancient astronomers, as well biological life cycles also give some matches for a different rotation period, ancient calendars ect.... give reference ect...
One thying seems clear humans survied or came in to existance in that condition.
