First off, an 'argument' isn't an argument in the same way as a shouting boyfriend and girlfriend disagreeing on who's turn it is to wash the dishes is. A philosophical argument is like a theory which is backed up by reasons to think that the theory is true.
Here's one that's a theist favourite: The Kalam Cosmological Argument, as made famous by William Lane Craig.
P1: Everything that begins to exist has a cause.
P2: The universe began to exist.
C: The universe has a cause.
The 'P's are called premises. The 'C' is the conclusion.
There are two things to think about when working with one of these arguments.
First we look at whether the argument is sound or valid. This means that we have to figure out if the C is what definitely follows if the Ps are true. It's a bit like maths. Does P1+P2=C in the same way that 2+2=4? That's not algebra, that's just figuring out the logic of the argument.
