From those "questions worth asking" it seems to me you should be prepared for a stonewall of IDiocy, mostly reducible to endless canards about information and complexity. I wouldn't be surprised if they start babbling Dembski propaganda directly. The "is any life really simple?" and "where did the instructions come from?" is a dead giveaway that that's what they intend to do. Baffle the credulous with tales of unfathomable complexity and useless appeals to computer-programming analogies, complete with bullshit expressions like "algorthimically defined mathematical information-instructionals" or something like that.
A good example of ID-shitspeak, as I like to call it, is this paper ID paper:

Genetic sequence complexity is unique in nature
"Complexity," even "sequence complexity," is an inadequate term to describe the phenomenon ofgenetic "recipe." Innumerable phenomena in nature are self-ordered or complex without being instructive (e.g., crystals, complex lipids, certain polysaccharides). Other complex structures are the product of digital recipe (e.g., antibodies, signal recognition particles, transport proteins, hormones). Recipe specifies algorithmic function. Recipes are like programming instructions. They are strings of prescribed decision-node configurable switch-settings. If executed properly, they become like bug-free computer programs running in quality operating systems on fully operational hardware. The cell appears to be making its own choices. Ultimately, everything the cell does is programmed by its hardware, operating system, and software. Its responses to environmental stimuli seem free. But they are merely pre-programmed degrees of operational freedom.
My blue. The paper is full of idiotic gems like that, designed to baffle people with fancy talk.
Or later in the paper, he almost orgasms from the complexity crap:
Functional Sequence Complexity (FSC)
A linear, digital, cybernetic string of symbols representing syntactic, semantic and pragmatic prescription; each successive sign in the string is a representation of a decision-node configurable switch-setting – a specific selection for function.

How did life begin?
At first I would concede that we don't know how it began and supply it with a reminder that using this as a platform to argue that we can't figure it out and never will is an argument from ignorance, in addition to being a pathetic and defeatist attitude to scientific problem solving. And then of course there's the fact that they want to shovel god in to a gap here.
Second, just because we don't know how life
actually began doesn't mean we don't have a pretty good idea for how it
could have. What is particularly interesting here, is the information canard that they are probably dying to boil it down to, and here one would simply have to provide examples of naturally occurring information generating and information changing systems, like sand-dunes and the growth of crystals.
Is any form of life really simple?
Noone thinks modern life sprang into existence fully formed the way it is now. This is simply a strawman question, purposefully engineered to baffle the ignorant with complexities.
Where did the instructions come from?
There are no instructions anywhere. There are only molecules reacting to molecules according to the laws of physics and chemistry.
Edit : Well, if they are going to go semantic on you and attempt to define functional genes into being instructional entities, the problem is merely one of evolution. So the answer then becomes : They evolved.
Has all life descended from a common ancestor?
Yes. The most compelling evidence for that is found not only in the near-universality of the genetic code(
which is itself an evolvable system) but in the progressively lesser homology in sequence you find in the genes of increasingly distantly related life. The simple fact is that every way in which we can test for common ancenstry, the evidence testifies to it with remarkable interdisciplinary consilience. If someone wants to argue that life was designed and didn't evolve with common ancestry, they will have to concede the designer set up life to look evolved. Everything else is lunacy.
Is it reasonable to believe the bible?
No.
