There may be aliens out there - statistically it is likely - but the burden of proof for the supernatural lies with he making the claim.
God can't be proven as though he were Coulomb's Law. The givens of faith are that God must be believed, for He will not give an adulterous generation any sign but the sign of Jonah. It seems to me an indissoluble either/or where each side is acceptable only on its own terms and essentially madness on the other's.
