Asking whether a belief X is justified can lead to very opinion-based answers (e.g., Does life have a natural or supernatural origin?), but I don't think this necessarily has to be the case if we constrain the scope of the question to be answered from very specific epistemological theories of justification, namely, evidentialism and process reliabilism.
First, some definitions:
Evidentialism
Evidentialism in epistemology is defined by the following thesis about epistemic justification:
(EVI) Person S is justified in believing proposition p at time t if and only if S’s evidence for p at t supports believing p.
As evidentialism is a thesis about epistemic justification, it is a thesis about what it takes for one to believe justifiably, or reasonably, in the sense thought to be necessary for knowledge. Particular versions of evidentialism can diverge in virtue of their providing different claims about what sorts of things count as evidence, what it is for one to have evidence, and what it is for one’s evidence to support believing a proposition. Thus, while (EVI) is often referred to as the theory of epistemic justification known as evidentialism, it is more accurately conceived as a kind of epistemic theory. In this light, (EVI) can be seen as the central, guiding thesis of evidentialism. All evidentialist theories conform to (EVI), but various divergent theories of evidentialism can be formulated.
Process reliabilism
Reliabilism encompasses a broad range of epistemological theories that try to explain knowledge or justification in terms of the truth-conduciveness of the process by which an agent forms a true belief. Process reliabilism is the most common type of reliabilism. The simplest form of process reliabilism regarding knowledge of some proposition p implies that agent S knows that p if and only if S believes that p, p is true, and S’s belief that p is formed by a reliable process. A truth-conducive or reliable process is sometimes described as a belief-forming process that produces either mostly true beliefs or a high ratio of true to false beliefs. Process reliabilism regarding justification, rather than knowledge, says that S’s belief that p is justified if and only if S’s belief that p is formed by a reliable process. This article discusses process reliabilism, including its background, motivations, and well-known problems. Although the article primarily emphasizes justification, it also discusses knowledge, followed by brief descriptions of other versions of reliabilism such as proper function theory, agent and virtue reliabilism, and tracking theories.

Abiogenesis
Abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities on Earth was not a single event, but a process of increasing complexity involving the formation of a habitable planet, the prebiotic synthesis of organic molecules, molecular self-replication, self-assembly, autocatalysis, and the emergence of cell membranes. The transition from non-life to life has never been observed experimentally, but many proposals have been made for different stages of the process.

Is belief in abiogenesisabiogenesis justified under evidentialism and process reliabilism? Is the belief justified according to one epistemological framework of justification but unjustified according to the other? Is abiogenesis simultaneously justified according to both frameworks?
