God stopped speaking for 400 years because there were no prophets to deliver his messages during that time period.
In God's will
The Kingdom of God is inside you and all around you! Jesus said it is My voice you hear.
The period of silence from God for 400 years is traditionally believed to be between the last writings of the Old Testament prophets and the birth of Jesus Christ, as there are no recorded prophetic messages during this time in the Bible.
These are the years in which there was no Prophet or teacher ordained of God and thus no fresh 'word of the Lord' or revelation. Thus in this sense there was 'silence' although of course God was still speaking through the ongoing relevance of previous messages.
God was silent for 400 years in the Bible because it was a period known as the intertestamental period, where there were no prophets or recorded divine messages. This time of silence ended with the arrival of John the Baptist, who prepared the way for the coming of Jesus Christ.
The Bible verse referring to "God being silent for 400 years" signifies a period of no direct communication or intervention from God in human affairs. This period is seen as a time of waiting and anticipation for a new revelation or intervention from God.
In Jewish legend prophecy withdrew from the world when the Temple, God's link to His people, was destroyed. The prophets alive at the time remained, but the easy communion with God died out with them.
The interval between the Testaments is often referred to as "The Silent Centuries."
The period of 400 years during which God did not speak is often referred to as the "silent years" between the Old Testament and the New Testament. This time frame is not explicitly stated in a specific verse, but it encompasses the period from the last book of the Old Testament, Malachi, to the beginning of the New Testament. This gap highlights the prophetic silence before the arrival of John the Baptist and Jesus Christ.
I believe that the Mormons (at least the Church of Jesus Christ of Latter-day Saints) are speaking the truth of God. Of course, that may just be because I am an LDS, but I still strongly know and believe that we are speaking the truth about God.

Scentifically speaking: no, God doesn't exist and evolution is an entirely natural process.Religious-conservatively speaking: no, evolution isn't real. God made everything the way it is now.Religious-liberally/moderately speaking: yes, evolution is God's way of making his work happen.
