Well, Oi, I just do not have the time to visit all the websites or read all the books members recommend to each other. If anything, I should be off, writing my own books, etc. So, I would appreciate it if you would post your claim and we can go from there. I am guessing you are referring to some sort of online apologetic site or otherwise. I encourage everyone to be careful here. I made an extensive study of major online apologetic websites, from Answers in Genesis to Matt Slick to James Patrick Holding. I also had loads of correspondence with these individuals. I realize these sites can appear very seductive to lay persons. However, to those of us who have been lucky enough to receive an advanced education in theology, science, biblical studies, etc., these sites appear for what they really are: just the unqualified judgments of totally unqualified individuals. Indeed, the whole field of apologetics is flooded by such websites, books, videos, etc.
Now regarding the question you asked about about how do we know you were abducted by aliens or no. Good question. However, it touches only on the surface of the deeper issue here, which, to me at least, is this: How do I know , how can I be sure that my senses have not deceived me into believing I have received an email from you, asking me how I can know whether or not you were abducted by aliens? The senses are deceivers, my friend. Suppose you and I were look out a window. We would both say we saw people walking around out there. Totally bogus claim. The senses have deceived us. The senses can give only a very abstract impression of reality, they cannot connect us to the concrete and the particular. For all we know, we could be looking at automated clothing racks covered with clothing. How do I know I( am not dreaming right now? I have had very vivid dreams. May all this is somehow a result of my being intoxicated. I have been known to overly imbibe, think my senses were in order, and then went stumbling, tripping, etc. How do I know , how can I be sure that you are anything but as figment of my imagination, an illusion implanted in my mind by God, for whatever reason? Berkley and Leibniz would agree with me. No wait. How can I be sure Berkeley and Leibniz are not anything but an illusion implanted in my mind by God. No, wait. How can I be sure that my concept of God implanting illusions in minds is anything but a mere illusion implanted in my mind by my subconscious? God, self, time, space, universe, these are all habitual ways we make sense out of our experience. But we cannot step out of ourselves to make sure these really exist. Best to assume the null hypothesis and claim that since we have no hard evidence God, self, world, time, etc., exist, they are but figments of our imagination that have nothing to do with what's really out there. Bottom line is that all I can be sure of is that I am doubting, thinking. The rest, including even whether I have a body, is all up for grabs. Hence communicating with you is an act of bare speculation on my part5. While I enjoy such whimsy, I've had enough for today, am signing off, will see you tomorrow. No, damnit, wait. Tomorrow? That's a mere figment of my imagination, as time does not exist.
