I'm sorry, but you're talking out of your hat. Nobody proposed that the Earth (or the universe) was billions of years old. There simply was no such hypothesis. Everybody "knew" that the Earth was under 30 million years old. When the geologists set out to measure (yes, measure) the age of the Earth, their prejudice, if any, lay towards that value. Their data told them that the Earth had to be far more ancient. The physicists scoffed...but ultimately data trumps theory. The geologists were correct.
Nowadays we have several completely independent methods of measuring both the age of the Earth and the age of the universe. The ages measured by these methods agree. The universe is 13.7 billion years old, and the Earth is 4.6 billion years old.
It is hard data that you are arguing against, very hard data.
