I have noted a few atheists make the claim that God does not exist because there is a 100% lack of evidence.
Who are these atheists?
Its a very famous atheistic apologetic shared by many.
Is it? Then why have I never seen anyone make such a statement? And considering that as good as everybody in my social circle is atheist, that would be kind of strange if such is "very famous" and "share by many", right?
I understand that lack of evidence can prove the non-existence of something. Like a PCR test for COVID 19. Its just an example.
Nope.
Absence of evidence is not evidence of absence.
A negative PCR test means it is "unlikely" you have covid. It doesn't "prove" you don't have covid.
Also, a negative PCR test is not LACK of evidence.
A LACK of evidence would be having NO test (and no symptoms).
Now for a COVID 19 test, there is a test called PCR. It is an very well defined test that is based on elimination. You eliminate the probability of having the virus infection.
Euh.... no.
The test attempts to detect virus particles.
The test is "negative" when it fails to find said particles in the sample provided.
This does not eliminate the "probability" of having the virus.
It just means that the test didn't detect it in the sample provided.
At best, it makes it "unlikely" that one has covid - assuming everything in the test went well (that the sample was representative, that the test was carried out well, etc etc etc - and even then you can have false negatives or false positives according to error margins)
So that's a lack of evidence it exists in you. But this has been developed because people know the virus, it has been identified and tested by scientists, and they have developed a specific test that would eliminate it.
No. They developed a test that can detect covid virus particles in a sample.
Not finding virus particles in the sample is not a "lack of evidence".
A lack of evidence would be having no test available at all.
So I would like to ask the atheists who use this argument about theism and God. What is the test you have developed to do this elimination?
There is no test. That's why there is a lack of evidence.
A negative PCR test is evidence against the proposition that you have covid. It doesn't "prove" you don't have covid.
If there would be a god-test, then a negative result would be evidence against the proposition that said god exists. It wouldn't "prove" that said god does not exist.
EDIT:
Also, this example of a PCR test shows quite nicely imo how theists confuse positive and negative claims.
The PCR test
does not test if you do NOT have covid!
The test tests the proposition "you have covid".
It does not test "you do NOT have covid".
It is a test to detect if covid is present.
It is not a test to detect if covid is NOT present.
So, it tests the proposition "you have covid"
There is NO test that tests the proposition "you do NOT have covid".
The same would be true for gods.
A god-test would test the
existence of a god. It would not test the non-existence thereof.
The proposition is "god exists" - and that is what would be tested.
A negative result would be evidence against that proposition.
It would not be evidence for (or against) the proposition "god does not exist" - because the test wouldn't be testing
that.
So to conclude: a negative PCR test would mean that there is no reason to accept the claim that you have covid. You
could still have covid. The test merely fails to provide you with a reason to believe said claim.
And isn't that exactly what atheism is about..........
The lack of evidence FOR the proposition of theism means that there is no reason to accept that proposition. A god
could still exist. There's just no evidence to believe that to be the case.
That's it.
