Everyone dies. Without exception. Some of us are just less able to deal with that fact than others. Hence the elaborate myths of eternal life if you just believe this or just do that. They are just that. Myths. You. Will. Die. Just like I will die, and everyone who reads this. That's the price of admission to life.Makes no difference, Atheist or Christian, Buddhist or Muslim, devout Hindu or any religion, people are accountable to the Creator, Jehovah God. That means anyone alive has to pay for his sins with his death, the penalty for sinning is death.
It is only the true Christian witness of Jehovah God that has the hope of surviving the end of this world and never having to die at Armageddon. That is a good reason to study your Bible with Jehovah's witnesses, to have the prospect of eternal life in God's new world of righteousness, and by getting your sins forgiven by the blood of Jesus, the Lamb of God.
It really isn't such a big deal, so long as you don't waste your life obsessing about death or trying to live forever.
