you say you want an evolution

Scientists have found new fossils in northern China of an early mammal that swam and burrowed, showing that mammals diversified long ago, even in the days the dinosaurs still ruled the planet.

So, is this evidence for evolution? Or is it another example of the extreme steps that some believe a deceptive and manipulative God is willing to use to see whether or not people really have faith in Him? In other words, a God who is so insecure that He has to test those who worship Him by planting tons of evidence supporting the Theory of Evolution to see if it will weaken belief in the biblical truth that Earth was created in 4004 BC?
