See, it's typical for extremists like atheists and religious fundamentalists to resort to superlative arguments like yours.
1) I'm not comparing scientific "beliefs" with religious beliefs. So you can burn that straw man premise for starters.
2) No it doesn't always stay "deaded". It's pretty obvious that science is dynamic and our knowledge of our world continues to evolve.
Are you familiar with the the scientific theory of Phlogiston? If not, look it up.
How about, arguably the greatest scientific protagonist of all time, Isaac Newton's Corpuscular Theory of Light? Why do you think it took precedence over Christiaan Huygens' Wave Front Theory of Light which provided a more accurate description and prediction of the interaction of light with matter? And then later in the 20th century, Feynman's Quantum Electrodynamics.
And these are just a few examples.
Of course there's loads physical evidence supporting a non-flat earth, satellite pictures being the most compelling, but still it's just a bunch of physical evidence which does not constitute a complete and absolute description of reality. But let's keep the convo shallow for now.
There are many rational beliefs that can not be scientifically verified or "proven". Aesthetic judgments for example.
Science is permeated with "unprovable" assumptions. For example, Einstein's Special Theory of Relativity hinges on the assumption that the speed of light is constant in a one-way direction between any two points A and B. This BELIEF can't be scientifically "proven" yet this theory is one of the gems of contemporary physics.
Think about these things and give it a sec to marinate ...
I can tell Science is not your thing.
