if you was to lie down at noon so you were facing the sun, then go out in six months timeand lie in the same place at the same time, would you still be facing the sun.?
if the earth rotates once every day and goes around the sun once every year. then surly you'd be facing away from the sun the second time you did it.
if you don't understand this simple thing then get two balls, put a mark on one(earth),so the mark is facing the other one(sun).now rotate the earth as it moves around the sun and you'll see that when you get half way around, if you have done a complete number of turns with the earth, the mark will be facing away from the sun.

Days are counted as complete turns relative to the sun, so you are always facing the sun at noon. If you did the turns relative to the room you're in, you're modeling sidereal days. A sidereal day is one turn of the earth relative to the stars, 23 hours, 56 minutes, four seconds. If you go you at midnight six months apart, you will see that relative to the stars, you are facing in opposite directions.

A solar day - the time taken for an object to be in the sky at the same place again - is what we normall mean by a day, and is arbitrarily set to 24 hours. It includes the small advance due to the movement of the earth around the sun.

A sidereal day - broadly the time taken for the earth to complete a single rotation on its axis - is 23 hours, 56 minutes, 4.1 seconds .

If you used the sidereal measure of the day you would indeed be facing away from the sun.

The earth has seasons because the axis of the earth is not perpendicular to the plane of orbit. As the earth orbits the sun, the angle made by "direct sunlight" changes. In summer, the angle is closer to 90º, in winter it's the most oblique.
So, since that angle is changing, you cannot state that the sun's position in 6 months will be exactly opposite its position now.
Finally, if you go out at noon on two different days, what makes you think it'd be the middle of the night on one of those days? Noon is defined as midday, while the sun is out. If the sun's on the opposite side of the planet, it's nighttime.

There would be a slight difference in the position of the sun after six months time. The earth does rotate around itself and revolve around the sun the same way, but the slight difference would arise with the tilted axis that the earth has. That's the reason we have seasons. If its summer the first time, after six months it would be winter and vice versa and so the sun's rays would be more slanted in winter time. Anyhow you answered your own question.

Solar noon is when the sun appears the highest in the sky (nearest zenith), compared to its positions during the rest of the day. It occurs when the Sun is transitting the celestial meridian. This is also the origin of the terms ante meridiem and post meridiem. At solar noon, the sun is due south in the Northern Hemisphere, and due north in the Southern Hemisphere. (Actually, this is not strictly true, but the maximum difference between noon and sun due-south is a mere 16 seconds of time at 45 degrees North latitude, and 3 minutes at 85oN.) The sun is directly overhead at solar noon at the equator on the equinoxes; at Tropic of Cancer (latitude 23½°N) on the summer solstice in June; and at Tropic of Capricorn (23½°S) on the winter solstice in December.

If you lie down at noon facing the sun in July from the North Pole, after 6 months you wouldn't see the sun at all !!!

basically the sun rises in the east and sets in the west even though it may appear in a slightly different place through out the year if your assumption is correct please explain how one of the earliest forms of judging time the sun dial would work

From Earth, it will appear that the sun is still directly overhead, even though it's not.
