Another way of saying "evidently," their favourite word! For an interesting exercise do a search for that word in the Watchtower library and see how many times they use it - you will be amazed. Especially when you realise that each time they use it they are making an assertion for which they actually have no evidence...
The second one is "really".
The Scientism cult loves the "evidence" too. Evidence and "just", "only", "merely" (just neurochemicals, only natural laws, etc..).
The gospel of Scientism is the "theory of everything". They say this theory of everything will be the unification of quantum mechanics (cults love the quantum) and the theory of relativity. This unification will explain things like why you prefer jazz instead of hip-hop and things like that.
Evidently is a cult.
