In the beginning, God created the heavens and the earth. — Genesis 1:1 (ESV)
“The cosmos is all that is or ever was or ever will be.” — Carl Sagan, from Cosmos.
Which of these two quotes is a scientific statement, and which is a religious statement?
The initial reaction most people—including Christians— have had when I have asked this question is that the quote from Genesis is a religious statement, and the quote from Sagan is a scientific statement. In reality, both statements are religious or philosophical in nature, but only the Genesis quote is fully compatible with the universe as we know it.
I won’t dispute that the quote from the Bible is a religious statement. If religion is about God and his relationship to the universe and humanity, then Genesis 1:1 is clearly a religious statement.
Carl Sagan’s famous Cosmos statement is also a philosophical—and I would say religious—statement. Sagan had not observed that “the cosmos is all that is or ever was or ever will be,” nor had he nor any other scientist done an experiment which proved that God doesn’t exist or isn’t necessary. In other words, Sagan had not used anything like “the scientific method” to arrive at his conclusion, and his Cosmos quote is a philosophical statement, not a scientific one.
Atheists such as Sagan would say that science has explained everything from nuclear fusion to sexual reproduction without any need for inserting God into the process and so their faith that there is no God is justified (faith is the right word, even if they would scramble to say it in a different way). But in doing this they are confusing categories. It is one thing to say that stellar evolution or meiosis can be explained without inserting a “God did it” step. Christians do not insert a “God did it” step into these processes either. However, it is an entirely different matter to explain why there is a cosmos at all. This question is outside of science, and is one that theists have a better explanation for than do atheists.
Many dismiss the Christian belief that God created the entire cosmos—matter, energy, space, time, and laws—as coming from a primitive myth. By “cosmos” I mean “everything that is or ever was or ever will be,” which would include the multiverse (if there is such a thing) beyond our observed universe, but would not include God. Only one of the following statements, however, is actually compatible with the cosmos as we know it:
“In the beginning, God created the heavens and the earth.”
“In the beginning, nothing created everything.”
In the universe we live in, things do not pop into existence completely out of nothing. I am not talking about random quantum fluctuations creating subatomic particles here and there, because these particles are not truly popping up out of nothing. By nothing, I mean nothing — no space, time, matter, energy, nor laws. Because of this, it is incompatible with what we know about the cosmos—that is, it is incompatible with science—to believe that the cosmos came from absolutely nothing, or that it somehow created itself.
On the other hand, it is compatible with the universe as we know it (i.e. science) to advocate that it was caused to exist by something completely outside of it. There is absolutely no scientific reason, therefore, for a scientist to not accept that “in the beginning, God created the heavens and the earth.”
