Jon:
We cannot discredit God until we find a different explanation.
You mean 'rule out a miracle' not 'discredit God.'
I know the two ideas are linked in the minds of some people. But they are far from being the same thing.
At the same time, all explanations are equally valid which explain the event.
No, they are not.
Occam's razor, remember. It really works.
We can explain Kent Hovind's tax problems any number of ways. Among some of the explanations: (1) Hovind and his wife evaded taxes; (2) Hovind and his wife are citizens of an invisible country apart from the United States and thus are not obliged to obey US laws even though they live and work inside US borders; (3) Hovind and his wife actually paid their taxes in full, but invisible space unicorns from the planet Zembar vacuumed all the money out of government accounts and falsified all the records to make it appear the Hovinds were up to no good, then programmed IRS agents to remember events that never took place and programmed the Hovinds to forget all the taxes they really paid and say outrageous things in their own defense, just so the unicorns could enjoy a good laugh about the whole gag at the next Interplanetar Invisible Space Unicorn Association convention on a secret asteroid in the Crab Nebula.
Are all these explanations of the event equally valid? No.
Your assertion is manifestly false for additional reasons if you mean to discuss
scientific validity. To possess scientific validity an explanation has to be supported by observable data that can be tested.
