Scientists like their job. That's why they try to appease the questioning minds of non-scientists in religious science ways... science theory as fact. If they didn't, the people would lose all their respect for scuentists. Why? Because REAL science takes way too long to find the answers for the most important questions... Heaven, Hell, God, evolution, life without end, lots more.
REAL science are done by REAL humans, who may or may not have burning questions about whether or not there are other life forms apart from the observable and discoverable ones, being studied and analyzed to date. This is not what REAL science, being conducted by REAL Scientists do: it does not presuppose any of the things the words you used may or may not refer to,
id est "god, heaven, endless life" etc., which, when analyzed, represents mere speculative (linguistically articulated)
social constructs - at best.
