Isaiah and the Dead Sea Scrolls

If it were inspired by God and I believed all that is written is definitely inspired then I would believe that all that is written would have been translated perfectly. The idea is too immaculate to completely comprehend though. Who first found these scrolls and why did we automatically trust them assume them translate them and pass them on? Is there anything that we have in our Bible that was written and translated before historians found artifacts that proved it was identical? And even that has falsity's.. if you're going to go that far to believe something, why not take it all the way through? Someone could have easily wrote something, true or made up, then copied it passed it around and then the original got lost and buried.. so over the years we think w're passing something great around then all the sudden we find the original and it matches pretty closely to what we already have. When I put it like that, it makes it sound less impressive to have found something like that. What we percieve a long time in our minds may not really be a long time, or maybe it's longer. All of the variables that we create in our minds are limited by our human brain. We'll never be able to fully comprehend anything/everything.
