Well, I know this attempt at education will most likely be ignored, but I'll take a stab at this question, PeaceCrusader.
Some common characteristics of an organism that is alive (I assume you mean humans here, because of the use of the phrase "you who are alive):
1) Is contiguous and maintains homeostasis. It's hard to imagine an alive human who can't maintain a physical boundary to their body and has no control whatsoever over their temperature, pH level, oxygen saturation, etc.
2) Has a metabolism - needs to intake nutrients (or "burn" stored molecules) and produces useful energy for work.
3) Has at least the theoretical ability to reproduce, even though it may not be used in practice or may no longer be functional / may be damaged.
4) Can regrow certain cells / bodily structures and can recover from injury.
5) Can respond to stimuli within the range of human perception.
Not every human meets all 5 of the above, but I'd venture to guess that if you can't meet *any* of the 5, you're pretty much dead. That's my stab at it.
Let me guess - your explanation has something to do with having / not having a spirit / soul, right? While I personally believe that such ethereal constructs exist, the scientist in me can't doesn't allow that personal belief to enter the realm of science. Which is where the definition of "dead or not dead" firmly lies.
We could get into some interesting side-threads regarding fables of homunculi / golems / revenants / similar creatures that are alive but have no spirit / soul or dead but have a spirit / soul but I don't see anything productive coming out of that, because there's no scientific proof of a spirit / soul in the first place.

Very well said, PiedPiper, of some common characteristics of a living person. But I disagree with you when you say that “if you can't meet *any* of the 5, you're pretty much dead.” A baby is alive although he/she cannot reproduce yet. Is he/she dead? No. He/she is alive.
A person’s limb is cut off and becomes an amputee. Is he/she alive or dead? Can he/she regrow an amputated limb?
Because you are an atheist, you do not believe in spirit. FYI, a person is alive because his/her spirit is still in his/her physical body while a person is dead because his/her spirit has left his/her physical body. Is this not logical?
The Holy Bible which is from the only true God says in Genesis 2:7, “And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.” He breathed His spirit into the person that is why he/she became alive.
And in Ecclesiastes 12:7, “Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.” What happens when we die? The physical body which is soil or dust, and inanimate, shall return to the earth where it came from, and the spirit in his/her body shall return to God who gave it. The Holy Bible explains it, isn’t it? Do you call the Holy Bible a fairy tale?
The same thing happens to Ka Apaz. She is standing in front of the altar. When her spirit leaves her physical body, it collapses to the floor. Then this holy spirit enters her body and it rises again. Please read
http://aristean.org/wp086.htm titled “How the Holy Spirit talks to people”.
A living person is hot while a dead person is cold. Why? Because the spirit is hot. The holy spirit we (plural) talk to blesses us when we say, “Mano po, Ama” (people’s greetings to the spirit not physically kissing his hand but by just saying it), replies: “May the Father be with you from me from the Father, may your hearts feel the heat and flame of the Holy Spirit, may your soul feel the grace of peace, may the Lord be with you.” Our response: “Thank you for being worthy.”
You see, the spirit says, “the heat and flame of the Holy Spirit”. As long as a person is alive, “the heat and flame of the Holy Spirit” is still in his/her physical body. The Holy Spirit is God that is why God knows everything that we say or do, and even think. When we pray, even without uttering any word from our mouths, God knows what we are praying for. He knows if we are sincere or not.
FYI, the Holy Bible was written by various people at various times at various places and languages. And yet, we find unity in it.
