Peer scientists reviewing Wegener’s hypothesis of continental drift rejected his notion because

• His evidence was too few to make a valid conclusion 
• He did not explain how continents move and what moves them
• His evidence was not clear in showing  how continents were joined
• He lied by including false evidence
