My "motives" are the truth. The scientfic method that you dismiss is how we reach the truth, we prove it and we know.

Belief is the enemy of knowing.

You believe they sent probes (little spaceships that flew 93 million miles away and sent us radio signals back from there). Again, you have no proof of that, you just trust it and believe it.

Actual science requires testable, observable, measurable and repeatable facts, not just belief.

Without knowing, all you can do is believe. That's not good enough for me.
