The Paradox of the Trinity

In order to explain our existence, we don't have a coherent or non paradoxical or non contradictory account. So I guess we end up with three options, each of which do not make rational sense to us. And yet one of these must be true or else we wouldn't exist to talk about it. The Trinity basically fits perfectly with the idea of the bringing together of being and becoming in the both option because it take what would the both option entail? Something that is timeless.
