Now I am a firm believer in the existence of God, but most of my friends are atheist (even though they are baptized Catholic and are preparing for confirmation this year) and I would like to know the best evidence for His existence.
There is none. Sorry, but that’s just the way it is.
I like the argument from contingency from Thomas Aquinas. Check out this video from bishop Barron

Aquinas is begging the question.
I personally think that historical evidence is even better than philosophical.
Well, it would be, given that philosophy doesn’t
ever produce actual evidence.
There’s plenty of evidence for the resurrection and for Jesus.
There’s no evidence for the resurrection. There
is evidence that the resurrection story was borrowed from earlier mythology/
The fact that his disciples were ready to die for him.
Begging the question. No “facts” are in evidence.
The gospels and even the gnostic texts.
Which are contradictory - as you might expect when fairy stories are passed down over decades of camp-fire recitals
And many trustworthy people throughout history who have claimed that they saw Jesus, Marry or other saints.
There is some evidence that a bloke called Jesus existed. None at all that he was the son of god or worked any miracles or was resurrected.
Ultimately, if you want to make a truth claim about the existence of god, you need to be able to provide convincing evidence. Evidence that is proportionate to the claim being made.
The problem is that Christians claim that this God character, who is apparently male, created the world in seven days, hears all our thoughts and knows everything. There’s zero evidence for any of this (and if the claim is true, there really should be) and in fact, plenty of evidence against. What there is also evidence for - abundant and corroborating evidence - is that the universe was created from a singularity and all life evolved from single-celled organisms through natural selection of random mutations, over billions of years. The evidence is simply denied by those who wish it didn’t exist - and I suspect you’re one of them - but that doesn’t make it disappear.
I’m not trying to get you to change your mind, OP - I’m aware that’s incredibly unlikely to happen - but to let you know that you’re unlikely to succeed in your implied aim of converting your atheist friends to superstitious belief, simply by quoting Aquinas etc.
