Now, now, Tik.
Get to know him first.
Stuck, you may want to point out that the National Geographic Channel is doing a special on the 10 plagues, Sunday, April 20.
This show is strictly from an archaelogical standpoint, but seems to corroborate the Biblical account of the Exodus.
You could point out how it's good to seek answers and explanations from other sources, and that we should use our God-given thinking abilities to try to figure out what really happened.
For example, the narrative reports that the killer disease plague (#5) wiped out all the livestock of the Egyptians, but not those of the Israelites.
Then, it's reported that the plague of hail (#7) killed every person and animal who had not taken shelter.
Are these non-livestock animals that were killed by the hail? Are the plagues listed in chronological order?
I would mention that it is not wrong to question; hopefully, this will set some minds to thinking.
Blessings.
