Look reporting other people ideas is not what truth means. Verifying that something is real or not requires a bit more effort. Only repeated experiment with the same results can confirm or dismiss a thesis. About the arc of covenant you know nothing, I know nothing and there is just noise about something that does not matter at all. If it exists or not is not going to change my life, being it a jew stuff or Welsh. Why do you even waste your time and care about that stuff?
