Oh and by the way, they have found the real Mt. Sinai in the Saudi desert which is very strong evidence that the jews passed through just as the book of Exodus records. You can probably buy the book on line - includes photos of the mountain ("The Mountain of Moses" I believe is the title). I believe the author is Bob Cornuke who sneaked into the site with his partner a few years ago. Not only did they find an altar with carvings of cattle (cattle in the saudi desert?) but the top 30% of the mountain was charred black as if scorched by fire - plainly seen in the photos and by the eyewitnesses. The scorching is not volcanic, btw. There you go...this ought to give you something to investigate...if you are interested.
So in sum, you look to find what you are looking for, with what you are looking with? That my friend is hopeful thinking and not any valid technique of historical study. "No evidence" (silence as you call it) surely is not disproof, but it surely is not support either. I was looking for evidence of support not evidence of a null hypothesis. Have you any archeological evidence at all that the Jews were ever slaves in Egypt?
Also, evidence that a burnt mountain with calf drawings is only support that someone was there, not the Jews. Evidence exists that there was an expelling of some EGYPTIANS from Egypt around that time.
