Worst Arguments For Christianity

[Pizza]

Analogical arguments like the Watchmaker analogy are weak. Apologists just compare universe to a watch or something man-made, list maybe one similarity, and ignore all dissimilarities. That's the definition of a weak analogy. The more dissimilarities you have and the less similarities you have the weaker the argument is. Obviously the universe is more vast and complex than a watch or anything man made.
Fine tuning argument just bold face assumes the the universe was designed for life and fail victim to the same criticism of other teleological arguments. But really does a universe in which life exists need explanation? Why can't it be just a brute fact?
Unlikely things happen all the time like winning the lottery! I'm just going to quote someone else who explains this better than I could.

So, the fact that it was extremely unlikely that Jim would win the lottery is no argument that the lottery was rigged, since it's always extremely unlikely that the winner wins, whoever it happens to be. Similarly for the fine-tuning argument: assuming that the fundamental physical constants of the universe were set randomly, any given setting is extraordinarily unlikely. However, given that there is a physical universe at all―and we know that there is―those constants must have some particular values. Therefore, something extraordinarily unlikely was bound to happen. It just so happens that those values made it possible for us to come into existence, but that's no argument that the lottery was rigged.
