Buddhism is atheist and doubt-oriented, but have no spirits in it so it can't be spiritual. Same thing to atheism.
Buddhism don't speak about love, but compassion.
And do not speak about spiritual but contemplation.
The human mind exists to contemplate the world. Let the universe teach you first, after that you can play with it.
Be convict that some supernatural being created the universe is a silly belief. The universe shown no sign to be created by a super mind.
