JOEL - If you are talking about aliens coming here from other planets, I suppose some Mormons might believe in this kind of activity, but not many.
If you are asking if Mormons believe that there are people living on other planets, then the answer is definately yes. Our scriptures tell us that God created many planets for His children to live on(Moses 1:33-35, D&C 76:24). However most Mormons believe that the only extraterestrials that have visited this planet are God and His angels who have appeared to a few people from time to time.
Given the fact that we know that there are others living on other worlds, it is possible that we have been visited by them, but very improbable according to what science has learned so far. Investigators usually discover ordinary explanations for most UFO sightings. Most scientists believe that there is not enough reliable evidence to connect these sightings with life from other planets. Also, the nearest solar systems that could possibly contain inhabited planets are so far away, that it would require technology that accommodates traveling at speeds faster than light in order to reach our own solar system.

MICHAEL - Do Mormons believe that God Himself came from another planet?

JOEL - There is a little understood doctrine in the Mormon Church that God the Father may have once lived on a planet in another universe as a man before he became an exalted personage and as a God created our universe. But not much has been revealed on this subject, so we don't talk about it much for fear of unproductive and false speculation. We do believe that in the eternities some of us might be able to become as God over our own universes.

MICHAEL - Do Mormons have any views on the Mayan calendar and the date of the end of the "Great Cycle" Dec 21st, 2012?

JOEL - No official opinion from the Church leaders on this although there may be a few Native American church members that are looking forward to this date.

MICHAEL - Why does Jesus say that even some who were standing with him on that day would still be alive when he returns?

JOEL - Here are the scriptures in question:

"Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:
So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
Verily I say unto you, This generation shall not pass, till all these things be fulfilled." (Matt 24:29-34)

"AND he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power." (Mark 9:1)

In these scriptures we believe that Christ was talking about some future generation of people that will be living during the time just before the Second Coming of Christ when all the signs spoken of in the previous verses are seen.
Joseph Smith produced a retranslation of those scriptures in Matthew 24 which can be found in The Pearl of Great Price scriptures in Joseph Smith-Matthew verses 1-25, which can be found at this page.

Joseph Smith retranslated verse 34 above to read:
"Verily, I say unto you, this generation, in which these things shall be shown forth, shall not pass away until all I have told you shall be fulfilled."

So in other words which ever generation of people happens to be around at the time all the signs are given, will still be there when Christ comes again. That time is still somewhere in the future.

The Mark 9:1 scripture is placed at the end of Mark 8 in the Joseph Smith translation of the Bible and is refering to the same thing as the Matthew scriptures.

MICHAEL - Most Mormons I have met have something about them that seems remote or distant. I would notice this about them BEFORE I found out they were Mormon. After while, I have been able to pick Mormons out and, so far, have always been right. Can you explain this quality?

JOEL - I am not sure what you mean by "remote" or "distant", but you are probably refering to the influence of the Holy Ghost in their minds and bodies and spirits. Some refer to it as a light in the eyes that distinguishes them from others.
Our Doctrine and Covenants scriptures explain:
"And the light which shineth, which giveth you light, is through him who enlighteneth your eyes, which is the same light that quickeneth your understandings. (D&C 88:11)

God tells us where this light comes from:
"I am the true light that lighteth every man that cometh into the world." (D&C 93:2)
"and the Spirit enlighteneth every man through the world, that hearkeneth to the voice of the Spirit."(D&C 84:46)

This light shows in our countenances as well as in our eyes.

There is a good talk by one of our church leaders on this very subject at this page.

The spiritual experiences we have in or lives and the blessings we receive that comes from living the Gospel of Jesus Christ, instills an inner peace, confidence, and happiness in our souls that shows on our faces.

MICHAEL - Do Mormons believe in reincarnation on this planet?

JOEL - No. Mormons do not believe in reincarnation. We only have one shot at life here on this earth. Once we die our souls go to heaven and stay there until the resurrection.

"For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors." (Book of Mormon, Alma 34:32)

MICHAEL - I know of someone who is intersexed (genetically). What are the Mormon views on intersexed individuals (hermaphrodites)?
(This individual felt looked down on by a Mormon man who obviously thought that this individual's gender was indistinct by choice.)

JOEL - In the Mormon Church's "The Family: A Proclamation to the World" we read:
"Gender is an essential characteristic of individual premortal, mortal, and eternal identity and purpose."

This means that all people including hermaphrodites have an eternal gender which is recognized by God, even if their mortal bodies carry some genetic defects. All people will rise in the resurrection with perfect bodies, which have had all their imperfections removed.
It doesn't matter if one is homosexual, heterosexual, or a hermaphrodite, the Gospel and commandments of God(which of course includes no fornication and no adultery) apply to everyone equally. And we are to treat everyone as a child of God with no prejudice against others regardless of their sexual orientation. We are all born into this world with weakneses that we must either overcome or learn to live with. If we live faithfully and not give in to our weaknesses God will eventually bless us with perfect bodies and reward us accordingly in the next life.
