When I told you there is no consensus on a definition for life, you don’t need to take my word for it. Just check out wikipedia!
It is still a challenge for scientists and philosophers to define life in unequivocal terms.[11][12][13] Defining life is difficult —in part— because life is a process, not a pure substance.[14] Any definition must be sufficiently broad to encompass all life with which we are familiar, and it should be sufficiently general that, with it, scientists would not miss life that may be fundamentally different from earthly life.[15]

I always keep this fact in mind anytime someone tries to extract too much significance out of the fact that it is likewise difficult to define things like ‘design’ and ‘intelligence.’ An attempt to build an argument around a selective demand for precise definitions is a sign that the attempt is rooted in a biased agenda and not an open-ended investigation.
