May God forgive me for what I say here. Existence of life is only until when the Earth exists. A belief in the Judgment Day say it will bring life to an end. An estimation is about 90 billion years - a crude calculation based upon the time when God created this Universe. We have been given five senses only and the sixth one is doubtful. No one knows until when is the existence of life on Earth or any other planet. Your question is itself an answer.
