Ok, for the third time: What makes you think you need to be "saved"?
Can you answer that without using the Bible and specifically without using a WT spin on it?
Why does he need to answer it without using the Bible? The Bible is the foundation of the Christian worldview, telling us how we got here, why is there death and suffering, why there are sedimentary rock layers all over the world. What we need to be saved from, and what God did to save us.
Yes, this involves presuppositions (as any world view does). There are many resources defending the Christian worldview, from many perspectives, showing its superiority to competing belief systems such as naturalism.
