It may seem like I'm jumping on a bandwagon that is convinced E.T. is responsible. As I've said, how should I know whether our earth is being visited or not? I have no proof but I tend to lean towards the possibility that someone is observing us; for certain I am leaning. We've had so many 'absolute' truths in the past that were subject to change as a result of new discoveries. How do we really know that the speed of light can't be surpassed or that warp speed etc. etc.. We think we know, & for certain at any given moment, but moments pass and all of a sudden we are looking through a new looking glass.
Paul indicates that magnetic technology, of human origin, is likely responsible for the bent stalk scenario ( or at least that's what I've infered). I've read that the changes in the seeds etc. are more reflective of microwaves or similar.
Paul, please elaborate on how magnetism is used to create these.
