Wow, no response to the substance of my post and an attitude to boot. But I'll respond.
Formally in science all conclusions are tentative. But the conclusions that the Universe is about 13.8 billion years old, the Earth is 4.54 billion years old, and life arose via natural causes and evolution are as well established as any scientific conclusion can be.
carbon dating is based on a constant which is not...
14C dating is based on the well-established fact of constant radioactive decay rates under terrestrial conditions and no other constant. E.g. there is no assumption of constant atmospheric 14C/12C ratio. We know that wasn’t constant.
... they have different results for the same piece
Nope. Although there are some creationist frauds that claim that.
what are you waiting to discover? make life in laboratory and this is the end of debate forever
Can't do that today. Probably will be able to do that in the reasonably near future.
But that won't end the debate. Creationists will claim to find fault. Whenever anything happens within 100 meters of a human being, creationists claim it doesn't count because of intelligence being involved.
This is supposed to be a discussion. Not an endless litany of falsehoods and ignorance. Bye-bye.
