Hi Ellie,
You seem overly concerned with what others believe. What feels true to you? It seems funny to me that you question science but trust someone's blog post and a conspiracy theorist. No one truly knows exactly how things will play out but evidence surely points to a bleak outcome for life on earth continuining. As uncomfortable as this is to contemplate perhaps it would be beneficial for people to look at how all our lives contribute and what we are really here for.
