I thought I would just explain how you can use the findings of science and history to narrow down the list of religions.

Falsifying a religion using science

Consider this argument:

1. Hindu cosmology teaches that the universe cycles between creation and destruction, through infinite time.
2. The closest cosmological model conforming to Hindu Scriptures is the eternally “oscillating” model of the universe.
3. The “oscillating” model requires that the universe exist eternally into the past.
4. But the evidence today shows the the universe, and time itself, had a beginning at the big bang.
5. The “oscillating” model requires that the expansion of the universe reverse into a collapse, (= crunch).
6. In 1998, the discovery of the year was that the universe would expand forever. There will be no crunch.
7. Therefore, the oscillating model is disconfirmed by observations.
8. The oscillating model also faces theoretical problems with the “bounce” mechanism.

Notice how I falsified the oscillating model with theoretical and experimental reasons.

The absolute origin of the universe out of nothing is also incompatible with atheism, Buddhism, Mormonism, etc. because they also require an eternally existing universe.

Falsifying a religion using history

Consider this argument:

1. To be a Muslim, you must believe that the Koran is without error.
2. The Koran claims that Jesus did not die on a cross. (Qur’an, 4: 157-158)
3. The crucifixion of Jesus is undisputed among non-Muslim historians, including atheist historians.
4. Therefore, it is not rational for me to become a Muslim.

I’m going to support the premise that Jesus was crucified by citing historians from all backgrounds.

Consider some quotes from the (mostly) non-Christian scholars below:

“Jesus’ death as a consequence of crucifixion is indisputable.” Gert Lüdemann

“That he was crucified is as sure as anything historical can ever be.”  J.D. Crossan

“The passion of Jesus is part of history.” Geza Vermes

Jesus’ death by crucifixion is “historically certain”. Pinchas Lapide

“The single most solid fact about Jesus’ life is his death: he was executed by the Roman prefect Pilate, on or around Passover, in the manner Rome reserved particularly for political insurrectionists, namely, crucifixion.” Paula Fredriksen

“The support for the mode of his death, its agents, and perhaps its co-agents, is overwhelming: Jesus faced a trial before his death, was condemned, and was executed by crucifixion.” L.T. Johnson

“One of the most certain facts of history is that Jesus was crucified on orders of the Roman prefect of Judea, Ponitus Pilate.” Bart Ehrman

That’s 7 famous historians: 3 atheists, 3 Jews and 1 moderate Catholic. The atheists, Ludemann, Crossan and Ehrman, have all debated against the resurrection of Jesus with William Lane Craig. Johnson is the moderate Catholic, the rest are Jewish historians. The Koran was written in the 7th century. That is why no professional historian accepts the Koran as more authoritative than the many earlier Christian and non-Christian sources for the crucifixion story. Many of the sources for the crucifixion are dated to the 1st century. It’s not faith. It’s history.

I have seen debates with Muslim scholars, and I have never once heard them cite a non-Muslim historian to the effect that Jesus was not crucified. To my knowledge, there is no historian who denies the crucifixion of Jesus in his published work.

Can Christianity be falsified by science or history?

Yes. If you prove that the universe is eternal than would falsify the Bible’s claim that God created the universe out of nothing. That would be a scientific disproof. If you could find the body of Jesus still inside a tomb, that would falsify the Bible’s claim about a resurrection. That would be a historical disproof. The nice thing about Christianity is that we make lots of testable claims. This is not make believe, this is knowledge. You can test this. And you should.
