So a couple of aeroplane crashes means aeroplanes don't work? You ever been in one? I mean, do yourself a favour.
Being a chemist I can't comment on your astronomical example, but of course science makes failed predictions from time to time. Unlike scripture, it makes no claim to be final "Truth".
How do you think science advances? The "plum pudding" model of the atom led to a failed prediction in Geiger and Marsden's experiment. From that failure we got the Rutherford-Bohr atom, which made a failed prediction (that electrons would spiral into the nucleus), so it was suspect from the start and required unexplained ad-hoc assumptions to get round the difficulty. But arising from it, within 20 years, thanks to Planck, Bohr, Einstein, de Broglie, Schrödinger and the rest of the boys, we got the quantum mechanical model of the atom we use today, whose predictions have been highly successful, explaining the Periodic Table, huge chunks of chemistry, atomic spectra and a lot else besides. But even that model fails to predict certain observations, such as the colour of gold........until the model is refined by adding relativity to it. And so it goes on, ceaselessly.
In science, a failed prediction causes excitement, rather than consternation, because it shows there is something new to learn about nature.
"Explaining" things by other beliefs is what mediaeval people did. Lightning strike? God did it. Plague? God's vengeance. Such "explanations" don't enable mankind to predict these things by understanding their natural causes. So, as explanations, they are clearly inferior to scientific ones. Is that really what you recommend we all do?
