By the way, I don't believe in reincarnation, does Buddhism make any sense without it? I'm an atheist.

welcome friend

the primary purpose of Buddhism is to bring freedom from suffering for human beings

suffering arises in many forms or around many situations, for example, death

for those that can accommodate impermanence & the selflessness of natural life, death will not lead to suffering for their mind & heart

but for others, to believe in reincarnation/rebirth can help reduce suffering concerning death

belief in reincarnation can also help people avoid the suffering of self-harm by encouraging the practise of good karma

but if the benefits of good karma can be seen with wisdom, there is no need to believe in reincarnation to develop good (harmless) karma

in its transcendent path (lokuttara), buddhism does not teach reincarnation belief as the means to extinguish mental suffering

kind regards
