Sheep normally live 10-12 years, so Dolly’s life was shortened considerably. Before the global flood, humans lived much longer, but something happened to shorten man’s life. Some think maybe there had been a vapor canopy in place that protected man from solar radiation and also evenly distributed temperatures on earth. Perhaps meteors pierced through that canopy at the time of the Lord’s water judgment, resulting in major precipitation. We know, for example, that there was once lush life in what is today the Sahara Desert. The theorized canopy, if depleted, could account for animals at the poles freezing, the vapor canopy no longer providing evenly distributed temperatures on the planet. Think of frozen mammoths and the Ice Age. The Bible tells about a global flood and also warns about a coming global fire (cf. 2 Peter 3). Is there an ark for us today? Yes, the FOUNTAIN OF LIVING WATERS (aka Creator Christ, Jehovah Jesus, and King of the Universe). Humble your heart before Him in faith before it is too late.
