No, this is the argument from the false alternative. If the naturalistic alternative fails, then that leaves only the naturalistic alternative. This remains to be seen. It has never seriously been tried.
Science just rules it out apriori.
But it isn't. These are just the rules that naturalists make, which theists need not play. Naturalists are entitled to the first go at trying to prove there was a naturalistic origin of life. If they succeed then they win. But if they fail, then such failure is automatic support for theism.
