Do you wish there's a god?

[Acrobat]

It's a scientific fact that our perceptions have literal blind spots and are in many ways easily fooled; and that's before even getting into bias. Fortunately we have devised a method to compensate for the limits of our perceptions, (magicians make their living from knowing a lot about those limits) the same method we use to outline those limits, basic observation, trial, and error at first; later, science. The best the argument you've outlined proves is that we perceive reality well enough not to be routinely killed by it before we finish raising our offspring; but that's 'not nuthin'.

Atheists believe this. In reality there's no real evidence, no studies etc.. that support the conclusion that science actually overcomes peoples strongly held biases. In fact we live in our world were such biases, even among smart people, create conflicting interpretations of the same data, and what the evidence actually means, or is capable of showing. The only thing being smarter seems to do, is just makes our interpretations that much more elaborate.

The problem is the atheists tend to imagine that things absent in certain observations, where there's hardly any real bias for one conclusion over the other, eliminates biases in conclusions where the observers/scientist do have strong biases.

There's no evidence that supposed method you refer to, actually compensates for the cognitive biases here.
