Aeris - Death, Life, Resurrection
This issue is so big that it deserved its own section on this site.

Can Aeris be resurrected?
Aeris was killed for a reason. Either you were enraged or just upset her death affected the way in which you played the remaining two disk of Final Fantasy VII. Furthermore she cannot be brought back in the Japan, British or computer versions. She cannot be brought back to life at all.

you can see Aeris after her death
-currently there are 6 ways to see Aeris after her death
1.An image of Aeris can be seen when you swap discs after Aeris dies. When you are prompted to change a disc, a random image will be shown. One of those images show Aeris staring at the Highwind.
2. This second sighting is a technicality. When we see Aeris being dropped in the tranquil water of the Ancient City, strictly speaking, we see an image of Aeris after her death.
3.  Aeris can also be seen via her infamous 'ghost' in the Midgar Church.
4. During disc 2, Cloud and Bugenhagen visit the Ancient City. While there, Bugenhagen replays Aeris' death inside a crystal. We can see Aeris there, dieing (again). This constitutes the fourth sighting of Aeris.
5. During the ending FMV, Aeris' hand and finally her face can be seen for a few moments. Sadly this is the last time we see Aeris in the entire game.
6. Aeris can be seen in the G-bike game at the Gold Saucer. When playing the game, glance at the person driving the utility truck. It is Aeris.

With the use of the gameshark and other computer editing tools it is possiable to activate areas of the game that may not have been accessiable. Players have claimed to have seen secert areas and well as certain scenes taken after the death of Aeris where she says a few lines.

Ghost in the Church
A polygon of Aeris is apparently visible in the Midgar church after Disc 1. If you have a sharp eye, you may be able to gain a glimpse of Aeris whenever you enter the church.There are actually two ghosts, one of Aeris standing in the church's aisle, and the other with Aeris tending the flowers. If one is to use the debug room via a gameshark they can find that the ghost are no accident. They were placed there for an unknown reason.

The Loveless Play and Aeris
Even though the words may appear somewhat inelligible, it is fair to assume they say the words 'My Bloody Valentine'. Apparently My Bloody Valentine is the name of a band who released an album in 1991. It was called 'Loveless'!

Right before you enter the North Cave, go back on to the bridge of the Highwind. Talk to Cid, and he'll ask you
"Hey Cloud, have you ever seen the play Loveless?"
 Reply "Yeah".
  Cid will then say, "I did, once, when I was interviewing to be a pilot in Midgar. I thought it would put me to sleep, and it did. Near the end, the guy next to me woke me up saying my snoring was too loud. All I remember is the end: the sister of the lead tells her lover 'I'll come back, even if you've moved on, because I know you'll be waiting.'"

Is the ending of the Loveless play a coincidence, or another cunning ploy by Square to tease the player?

Aeris vs. Aerith
Aerith was the name of the 'Flower Girl' in the Japanese version of Final Fantasy VII. When FFVII came to English shores, the name Aerith was changed to the more smoother Aeris. However this is even another spelling of the name, Earith. This can be fount using a gameshark and the debug room, proving she was originally called Earith. The 'th' is pronounced more like an 's', and hence Aeris and Aerith sound quite similar in Japanese

Death
Death is unadvoidable. It will happen sometime or another. Theres not alot one can do when they lose a loved one. Council with close friends usually helps, as seen how the group remembered Aeris and helped each other get along with their mission of defeating Sephiroth. By no means did they forget about her they constantly remembered what she had done, said and even her death. Aeris was admired by all the characters in one way or another, whetered they said it or showed it by actions.

Resurrection
As you may know by now their is no resurrection. Many were tricked into believing this because of certain hints in the game.

What does the ending of the game mean?
Well it means at no point after her death do you get to reacquire Aeris into your party.

Well this may sound silly but it is a fact and should be listed. Aeris does not return, nor was she meant to.

It shows that things aren't always meant to be, that life isn't a fairy tale.

If life was a fairy tale and the game meant to have a fairy tale and wonderful ending then Aeris would have come back, but she didn't. It was not meant to be that way.

You only get one chance to live, one blow can end it.

If you love someone tell them, share your life with those you care about and those who care about you.

Then where the heck is Aeris?

However, for a brief second you do get to see her face and hands.
At first I fount this wierd, as I am sure many of you reading this do.
After thinking about it for a while I came up with the conclusion that Aeris is not in fact dead. Thats right, no dont get your gameshark out yet or your copy of Final Fantasy VII. You still wont be able to play as her. Aeris is alive in your mind, your heart and in your soul.

Just like when you lose a loved one, a part of them still lives in you as well as everyone whos life was touched by that person. Even though they are not here in the physical world they are still in our hearts, minds, souls. One day we will meet again.

What does Cloud in Final Fantasy Tactics mean?
Well to gain Cloud into your party in Final Fantasy Tactics you must teleport him from the part. Since people do not live in the past that means that at some point Cloud died. There is no other explanation.
