We have a certain amount of proof that the past happened. We have fossils, architecture, artifacts, culturally modified trees - caves and earth. But strangely enough we don't have any evidence that there is a future. There are certainly indications that there is a future. We have predictions and calculations that assume there will be activities taking place beyond the present and sometimes the predictions and assumptions do take place. However, they always take place in the present. In fact, fossils and artifacts etc... can only be observed in the present as well and so can only be identified as being from the past by calculations and assumptions made from where they are found in the strata (etc..). Can someone present evidence that proves, without a doubt, that there is a future?
