-I do not think that humans have been here a mere 6,000 years. I think for example that Noah's flood may have happened 10-18,000 years ago and have triggered the ice age.
You sound like a very intelligent person. One who does not blindly believe. One that wants facts to back up assertions.
You will not do well in this religion. If you become baptised and still believe this foolishness, and worse yet attempt to speak your doubt audibly to another human being, at first the elders will be mildly upset. Should you state that you still believe it, you could be disfellowshipped for "causing divisions" in the congregation. Then your mother, who has now become more well adjusted, will be forced to shun you completely as though you are dead. No contact whatsoever unless there is some dire family emergency, and this is if she chooses to. If you have read stories on this forum, you will know that many posters found out their parents/relatives died through reading it in the newspaper.
You would have been forced to "believe" prior to 1995 that the generation that was alive and at an age of understanding in 1914 would not pass off the scene until Armageddon. Any who had voiced concern with this date were disfellowhipped. With the publication of the WT article in 1995, you could now no longer believe the prior information published for years as Divine Truth. If you question this, you could be disfellowshipped and shunned by your family........
As of this writing, a big controversy is going on with the year 1935. For many years the WTS said that the annointed calling was closed in this year, and that any who claimed to be of the annointed after this were clearly replacements. Now they are waffling over this teaching. As a matter of fact, the number that they count at the memorial each year of annointed "partakers" keeps increasing. I don't know exactly what an active JW is supposed to believe right now, but if you get baptized, you'd better find out, so that you do not reason on it for yourself. If you question what they currently teach you could be disfellowshipped and shunned by your family..........
If you do make a mistake in this religion, you may or may not encounter men that will strip you of every shred of dignity and self worth that you now posess. They did this with my teen daughter, a straight A student who had never been in trouble. She did not do half the things I did when I was a teen (not a witness) but they decided not to discuss the couple of stupid teen things she did do and to accuse her of fornication. For over two and one half hours they kept forcing her to read scriptures that compared her to Korah, Annanias and Sapphira (Who fell down dead because they lied) and everyone else in the Bible who was a bad example and was punished by God with death. When she finally would not admit to fornication (after they had admitted there was no witness, and no accusation of fornication by anyone) they told her they would not believe her. They demeaned and insulted her in every way possible, then made her read a scripture from Revelation that God views fornicators and liars as filth, and she would burn in the lake of fire with the devil and his angels. Then they disfellowshipped her. She is not shunned by her family. Instead, the WTS is shunned by us.
Whatever decision you make is yours to make. But please go into this with both eyes wide open. Oh, and you will never be allowed to look at this web site again. You could be disfellowshipped and shunned by your family..............
