The most basic scientific law is that matter cannot be created nor destroyed, only converted.

Where did all of the matter come from that created the universe? In other words, the "Big Bang" could have only converted some matter or energy into the current state. Where did it come from? Did it just spontaneously appear (create itself?)? If so, does that mean that the most basic scientific law is wrong, and as such, we should throw out every scientific conclusion that has any basis upon that law?

Just food for thought.

Here is something else to consider. If evolution is real, where are the in-between states? We do not see any evidence of a species converting to a new species. In other words, we do not have a starting species, an ending species, and mutations to connect the two. Basic observation skills of a 2nd grader can see this even.
