Just to throw in my two cents in.
Design always means the fantastic complexity of nature.
Not rounded stones.
Design is where a human being understands that such a complex thing could only of come from complex processes.
Design is likely or very reasonably to be seen where complexity of process can't be mere happanchance.
Therefore its reasonable to see design and not see evolutionary etc processes.
Then from there take on attempts to deny complex processes and replace them with simple step evolutionism.
Design equals complexity equals complex processes.
Sum. God plus his mechanisms.
