What real proof do some religions have for claiming that we are living in the worst times ever?

Right now, were are living in the most peaceful time in human history, back in the 10th centuries war wages on every year all over the world, from countries fighting over land, bandits attacking villages and pirates attack supply ships and gets sunk every month. If you're stealing, you get your hand chop off, or possibly hanged compare to now, most part of the world is living in peace except for some part of the middle east.
