How To Share The Gospel With An Atheist

Question: How should I share the gospel with an atheist? So I was saved about two years ago from, well, atheism, and I have a pretty atheistic family. And so I've been trying to share the gospel with them. Ever since I was saved. And just finally, recently, I'm engaged in a conversation with my sister, and she's wanting to get into a discussion about evidence and I'm just curious if you guys can touch on should I engage in that or not? And if not, at what point do you draw the line and you know, I've listened to sermons on not casting your pearls before swine and just kind of lost as to where to go from here.
