William lane craig’s cosmological argument AS Level Just explained more simply :)

1. William Lane Craig re-introduced the Kalam
Cosmological Argument which was originally formed
by the philosophers al-Kindi and al-Ghazi.
Four basic points: In 1933 Craig postulated a modern
version of the Kalam Cosmological argument:
1) Everything that began to exist, has a cause of existence
2) the universe began to exist
3) Therefore, the universe has a cause of existence
4) Since no scientific explanation (in terms of physical laws)
can provide a casual account of the origin of the universe,
the cause must be personal (explanation is given in terms
of a personal agent.
In order to answer the possibility that the
universe might be infinite, he made a second
point:
1) An actual infinite cannot exist
2) A beginningless temporal series of events is
an actual infinite.
3) Therefore, a beginningless temporal series
cannot exist.
Putting it simply: The universe
had a beginning therefore must
have had a cause for this
beginning. And since science
offers no explanation for the
universe’s beginning, the cause
must be personal.
Another way to explain what
William Lane Craig is saying is that
an ‘Actual infinite’ is nonsensical
as if we look at the year and date
it shows us that world had
beginning as we can’t really count
back in time. An example: If a Library was to actually have an
infinite number of books and there were infinite
amount of red and black books in this library.
With both red and black books combined, it
should add to the total number of books in the
collection. However this is ridiculous as the
entire set of books is never ending so therefore
can never be an equivalent between black and
red books.
