Hi Airduster. Well, it`s all pretty simple. I mean, there are lots of things you`ll need to learn, about 607bc, 1914, the UN-scandal etc, but to me, this is what it boils down to:
First of all, they claim to be a prophet. Well, actually, they are saying both things, that they are a prophet (when it`s time to get the members of their butts and work harder, and then, after a failed prophecy or when something goes wrong, they say that they are not. But usually, they say that they are):
"Wanted - a Messenger .. WHAT IS REQUIRED OF GOD'S MESSENGER .. More accurately, was there any group on whom Jehovah would be willing to bestow the commission to speak as a 'prophet' in His name, as was done toward Ezekiel back there in 613 B.C.E.? .. It is of importance to every individual on earth to identify the group that Jehovah has commissioned as his 'servant' or messenger. We must recognize and understand the warning that he brings. We need to take action on the warning to safeguard our lives, for they are in a danger as grave as that of the lives of Jerusalem's citizens as that city neared destruction. For this reason forthcoming issues of The Watchtower will further discuss the identity and work of Jehovah's commissioned messenger as revealed in His vision to Ezekiel." {WT Mar 15 1972}
"'They Shall Know that a Prophet Was Among Them' People today can view the creative works. They have at hand the Bible, but it is little read or understood. So, does Jehovah have a prophet to help them, to warn them of dangers and to declare things to come? .. IDENTIFYING THE 'PROPHET' .. These questions can be answered in the affirmative. Who is this prophet? .. This 'prophet' was not one man, but was a body of men and women. It was the small group of footstep followers of Jesus Christ, known at that time as International Bible Students. Today they are known as Jehovah's Christian witnesses. They are still proclaiming a warning .. Of course, it is easy to say that this group acts as a 'prophet' of God. It is another thing to prove it. The only way that this can be done is to review the record. What does it show?" {WT Apr 1 1972}
Secondly, they have a long track-record of coming up with prophecies that failed to come true.The predicted Armageddon in 1874, 1884, 1914 (yes, 1914 was the year Armageddon was going to come, not his invisible presence, this is something they came up with later on), 1915, the ressurection of the "prophets of old" in 1925, Armageddon in 1975, and before the literal generation of 1914 had died out, which they changed in 1995. These are to many articles to quote here, but you can read thru all of it here:

Read thru the "Large List of Predictions"-pages (not just predictions, all sorts of stuff), and then check with your yearbooks, if you are in doubt if these things were really said in the Watchtower. And then, while you are reading, keep this in the back of your mind at all times:
Deuteronomy 18:20 “But if any prophet presumes to speak anything in my name that I have not authorized him to speak, or speaks in the name of other gods, that prophet must die. 18:21 Now if you say to yourselves, ‘How can we tell that a message is not from the Lord?’ – 18:22 whenever a prophet speaks in my name and the prediction is not fulfilled, then I have not spoken it; the prophet has presumed to speak it, so you need not fear him.”
That is the summary. The "prophet" is a false prophet, and must die. But you have a lot to learn before you understand that. Search around the internet, just type in "watchtower society" or "Jehovahs witnesses" in Google, and you`ll get a ton of hits. Start your research.
